This article helps you choose settings for Windows 10, version 1909 (build 18363) that should result in the best performance in a Virtualized Desktop Infrastructure (VDI) environment. All settings in this guide are recommendations to be considered and are in no way requirements.

The key ways to optimize Windows 10 performance in a VDI environment are to minimize app graphic redraws, background activities that have no major benefit to the VDI environment, and generally reduce running processes to the bare minimum. A secondary goal is to reduce disk space usage in the base image to the bare minimum. With VDI implementations, the smallest possible base, or "gold" image size, can slightly reduce memory usage on the hypervisor, as well as a small reduction in overall network operations required to deliver the desktop image to the consumer.

Note

These recommended settings can be applied to other Windows 10 1909 installations, including those on physical or other virtual machines. No recommendations in this article should affect supportability of Windows 10 1909.

VDI Optimization Principles

A VDI environment presents a full desktop session, including applications, to a computer user over a network. The network delivery vehicle can be an on-premises network or could be the Internet. VDI environments are a "base" operating system image, which then becomes the basis for the desktops subsequently presented to the users. There are variations of VDI implementations such as "persistent", "non-persistent", and "desktop session". The persistent type preserves changes to the VDI desktop OS from one session to the next. The non-persistent type does not preserve changes to the VDI desktop OS from one session to the next. To the user, this desktop isn't much different to any other virtual or physical device, other than being accessed over a network.

The optimization settings would take place on a reference device. A VM would be an ideal place to build the image, because the state can be saved, checkpoints can be made, and backups can be done. A default OS installation is performed on the base VM. That base VM is then optimized by removing unnecessary apps, installing Windows updates, installing other updates, deleting temporary files, and applying settings.

There are other types of VDI such as Remote Desktop Session (RDS) and the recently released Azure Virtual Desktop. An in-depth discussion regarding these technologies is outside the scope of this article. This article focuses on the Windows base image settings, without reference to other factors in the environment such as host optimization.

Security and stability are top priorities for Microsoft when it comes to products and services. Enterprise customers might choose to utilize the built-in Windows Security, a suite of services that work well with or without Internet. For those VDI environments not connected to the Internet, security signatures can be downloaded several times per day, as Microsoft might release more than one signature update per day. Those signatures can then be provided to the VDI VMs and scheduled to be installed during production, regardless of persistent or non-persistent. That way the VM protection is as current as possible.

There are some security settings that are not applicable to VDI environments that are not connected to the Internet, and thus not able to participate in cloud-enabled security. There are other settings that "normal" Windows devices might utilize such as Cloud Experience, The Windows Store, and so on. Removing access to unused features reduces footprint, network bandwidth, and attack surface.

Regarding updates, Windows 10 utilizes a monthly update algorithm, so there is no need for clients to attempt to update. In most cases VDI administrators control the process of updating through a process of shutting down VMs based on a "master", or "gold" image, unseal that image which is read-only, patch the image, then reseal it and bring it back into production. Therefore, there is no need to have VDI VMs checking Windows Update. In certain instances, for example, persistent VDI VMs, normal patching procedures do take place. Windows Update or Microsoft Intune can also be used. System Center Configuration Manager can be used to handle update and other package delivery. It's up to each organization to determine the best approach to updating VDI.

Tip

A script that implements the optimizations discussed in this topic--as well as a GPO export file that you can import with LGPO.exe--is available at The Virtual Desktop Team on GitHub.

This script was designed to suit your environment and requirements. The main code is PowerShell, and the work is done by using input files (plain text), with Local Group Policy Object (LGPO) tool export files. These files contain lists of apps to be removed, and services to be disabled. If you do not wish to remove a particular app or disable a particular service, edit the corresponding text file and remove the item. Finally, there are local policy settings that can be imported into your device. It is better to have some settings within the base image, than to have the settings applied through the group policy, as some of the settings are effective on the next restart, or when a component is first used.

Persistent VDI

Persistent VDI is, at the basic level, a VM that saves operating system states in between reboots. Other software layers of the VDI solution provide the users easy and seamless access to their assigned VMs, often with a single sign-on solution.

There are several different implementations of persistent VDI:

• Traditional virtual machine, where the VM has its own virtual disk file, starts up normally, saves changes from one session to the next. The difference is how the user accesses this VM. There might be a web portal the user logs into that automatically directs the user to their one or more assigned VDI VMs.

• Image-based persistent virtual machine, optionally with personal virtual disks. In this type of implementation there is a base/gold image on one or more host servers. A VM is created, and one or more virtual disks are created and assigned to this disk for persistent storage.

  • When the VM is started, a copy of the base image is read into the memory of that VM. At the same time, a persistent virtual disk is assigned to that VM, with any previous operating system changes merged through a complex process.

  • Changes such as event log writes, log writes, etc. are redirected to the read/write virtual disk assigned to that VM.

  • In this circumstance, operating system and app servicing might operate normally, using traditional servicing software such as Windows Server Update Services, or other management technologies.

  • The difference between a persistent VDI machine, and a "normal" virtual machine is the relationship to the master/gold image. At some point updates must be applied to the master. This is where implementations decide how the user persistent changes are handled. In some cases, the disk with the changes are discarded and/or reset, thus setting a new checkpoint. It might also be that the changes the user makes are kept through monthly quality updates, and the base is reset following a Feature Update.

Non-Persistent VDI

When a non-persistent VDI implementation is based on a base or "gold" image, the optimizations are mostly performed in the base image, and then through local settings and local policies.

With image-based non-persistent VDI, the base image is read-only. When a non-persistent VM is started, a copy of the base image is streamed to the VM. Activity that occurs during startup and thereafter until the next reboot is redirected to a temporary location. Users are usually provided network locations to store their data. In some cases, the user's profile is merged with the standard VM to provide the user with their settings.

One important aspect of non-persistent VDI that is based on a single image is servicing. Updates to the operating system and components are delivered usually once per month. With image-based VDI, there is a set of processes that must be performed to get updates to the image:

• On a given host, all the VMs on that host, that are derived from the base image must be shut down / turned off. This means the users are redirected to other VMs.

• The base image is then opened and started up. All maintenance activities are then performed, such as operating system updates, .NET updates, app updates, etc.

• Any new settings that need to be applied are applied at this time.

• Any other maintenance is performed at this time.

• The base image is then shut down.

• The base image is sealed and set to go back into production.

• Users can log back on.

Note

Windows 10 performs a set of maintenance tasks, automatically, on a periodic basis. There is a scheduled task that is set to run at 3:00 AM every day by default. This scheduled task performs a list of tasks, including Windows Update cleanup. You can view all the categories of maintenance that take place automatically with this PowerShell command:

              Get-ScheduledTask | Where-Object {$_.Settings.MaintenanceSettings}                          

One of the challenges with non-persistent VDI is that when a user logs off, nearly all the operating system activity is discarded. The user's profile and/or state might be saved to a centralized location, but the virtual machine itself discards nearly all changes that were made since the last boot. Therefore, optimizations intended for a Windows computer that saves state from one session to the next are not applicable.

Depending on the architecture of VDI VM, things like PreFetch and SuperFetch are not going to help from one session to the next, as all the optimizations are discarded on VM restart. Indexing might be a partial waste of resources, as would be any disk optimizations such as a traditional defragmentation.

Note

If preparing an image using virtualization, and if connected to the Internet during image creation process, on first logon you should postpone Feature Updates by going to Settings, Windows Update.

To Sysprep or not Sysprep

Windows 10 has a built-in capability called the System Preparation Tool, (often abbreviated to "Sysprep"). The Sysprep tool is used to prepare a customized Windows 10 image for duplication. The Sysprep process assures the resulting operating system is properly unique to run in production.

There are reasons for and against running Sysprep. In the case of VDI, you might want the ability to customize the default user profile which would be used as the profile template for subsequent users that log on using this image. You might have apps that you want installed, but also able to control per-app settings.

The alternative is to use a standard .ISO to install from, possibly using an unattended installation answer file, and a task sequence to install applications or remove applications. You can also use a task sequence to set local policy settings in the image, perhaps using the Local Group Policy Object Utility (LGPO) tool.

Supportability

Anytime that Windows defaults are changed, questions arise regarding supportability. Once a VDI image (VM or session) is customized, every change made to the image needs to be tracked in a change log. At troubleshooting, often an image can be isolated in a pool and configured for problem analysis. Once a problem has been tracked to the root cause, that change can then be rolled out to the test environment first, and ultimately to the production workload.

This document intentionally avoids touching system services, policies, or tasks that affect security. After that comes Windows servicing. The ability to service VDI images outside of maintenance windows is removed, as maintenance windows are when most servicing events take place in VDI environments, except for security software updates. Microsoft has published guidance for Windows Security in VDI environments. For more information, see Deployment guide for Windows Defender Antivirus in a virtual desktop infrastructure (VDI) environment.

Consider supportability when altering default Windows settings. Difficult problems can arise when altering system services, policies, or scheduled tasks, in the name of hardening, "lightening", etc. Consult the Microsoft Knowledge Base for current known issues regarding altered default settings. The guidance in this document, and the associated script on GitHub will be maintained with regards to known issues, if any arise. In addition, you can report issues in several ways to Microsoft.

You can use your favorite search engine with the terms ""start value" site:support.microsoft.com" to bring up known issues regarding default start values for services.

You might note that this document and the associated scripts on GitHub do not modify any default permissions. If you are interested in increasing your security settings, start with the project known as AaronLocker. For more information, see "AaronLocker" overview.

VDI Optimization Categories

• Global operating system setting categories:

  • UWP app cleanup

  • Optional Features cleanup

  • Local policy settings

  • System services

  • Scheduled tasks

  • Apply Windows (and other) updates

  • Automatic Windows traces

  • Disk cleanup prior to finalizing (sealing) image

  • User settings

  • Hypervisor / Host settings

Universal Windows Platform (UWP) application cleanup

One of the goals of a VDI image is to be as light as possible. One way to reduce the size of the image is to remove UWP applications that won't be used in the environment. With UWP apps, there are the main application files, also known as the payload. There is a small amount of data stored in each user's profile for application specific settings. There is also a small amount of data in the 'All Users' profile.

Connectivity and timing are important factors when it comes to UWP app cleanup. If you deploy your base image to a device with no network connectivity, Windows 10 can't connect to the Microsoft Store and download apps and try to install them while you are trying to uninstall them. This might be a good strategy to allow you time to customize your image, and then update what remains at a later stage of the image creation process.

If you modify your base .WIM that you use to install Windows 10 and remove unneeded UWP apps from the .WIM before you install, the apps won't be installed to begin with and your profile creation times will be shorter. Later in this section there is information on how to remove UWP apps from your installation .WIM file.

A good strategy for VDI is to provision the apps you want in the base image, then limit or block access to the Microsoft Store afterward. Store apps are updated periodically in the background on normal computers. The UWP apps can be updated during the maintenance window when other updates are applied. For more information see Universal Windows Platform Apps

Delete the payload of UWP apps

UWP apps that are not needed are still in the file system consuming a small amount of disk space. For apps that will never be needed, the payload of unwanted UWP apps can be removed from the base image using PowerShell commands.

In fact, if you remove those from the installation .WIM file using the links provided later in this section, you should be able to start from the beginning with a very slim list of UWP apps.

Run the following command to enumerate provisioned UWP apps from a running operating system, as in this truncated example output from PowerShell:

                          Get-AppxProvisionedPackage -Online      DisplayName  : Microsoft.3DBuilder     Version      : 13.0.10349.0     Architecture : neutral     ResourceId   : \~     PackageName  : Microsoft.3DBuilder_13.0.10349.0_neutral_\~_8wekyb3d8bbwe     Regions      :     ...                      

UWP apps that are provisioned to a system can be removed during operating system installation as part of a task sequence, or later after the operating system is installed. This might be the preferred method because it makes the overall process of creating or maintaining an image modular. Once you develop the scripts, if something changes in a subsequent build, you edit an existing script rather than repeat the process from scratch. Here are some links to information on this topic:

Removing Windows 10 in-box apps during a task sequence

Removing Built-in apps from Windows 10 WIM-File with Powershell - Version 1.3

Windows 10 1607: Keeping apps from coming back when deploying the feature update

Then run the Remove-AppxProvisionedPackage PowerShell command to remove UWP app payloads:

            Remove-AppxProvisionedPackage -Online -PackageName                      

Each UWP app should be evaluated for applicability in each unique environment. You'll want to install a default installation of Windows 10 1909, then note which apps are running and consuming memory. For example, you might want to consider removing apps that start automatically, or apps that automatically display information on the Start Menu, such as Weather and News that might not be of use in your environment.

Note

If utilizing the scripts from GitHub, you can easily control which apps are removed before running the script. After downloading the script files, locate the file 'AppxPackages.json', edit that file, and remove entries for apps that you want to keep, such as Calculator, Sticky Notes, etc. See the section Customization for details.

Manage Windows Optional Features using PowerShell

You can manage Windows Optional Features using PowerShell. For more information, see the Windows Server powershell forum. To enumerate currently installed Windows Features, run the following PowerShell command:

            Get-WindowsOptionalFeature -Online                      

You can enable or disable a specific Windows optional feature, as shown in this example:

            Enable-WindowsOptionalFeature -Online -FeatureName "DirectPlay" -All                      

You can disable features in the VDI image, as shown in this example:

            Disable-WindowsOptionalFeature -Online -FeatureName "WindowsMediaPlayer"                      

Next, you might want to remove the Windows Media Player package. There are two Windows Media Player packages in Windows 10 1909:

            Get-WindowsPackage -Online -PackageName *media*  PackageName       : Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.1 Applicable        : True Copyright        : Copyright (c) Microsoft Corporation. All Rights Reserved Company         : CreationTime       : Description       : Play audio and video files on your local device and on the Internet. InstallClient      : DISM Package Manager Provider InstallPackageName    : Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.1.mum InstallTime       : 3/19/2019 6:20:22 AM ...  Features         : {}  PackageName       : Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.449 Applicable        : True Copyright        : Copyright (c) Microsoft Corporation. All Rights Reserved Company         : CreationTime       : Description       : Play audio and video files on your local device and on the Internet. InstallClient      : UpdateAgentLCU InstallPackageName    : Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.449.mum InstallTime       : 10/29/2019 5:15:17 AM ...                      

If you want to remove the Windows Media Player package (to free up about 60 MB disk space):

                          Remove-WindowsPackage -PackageName Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.1 -Online   Remove-WindowsPackage -PackageName Microsoft-Windows-MediaPlayer-Package~31bf3856ad364e35~amd64~~10.0.18362.449 -Online                      

Enable or disable Windows Features using DISM

You can use the built-in Dism.exe tool to enumerate and control Windows Optional Features. A Dism.exe script could be developed and run during an operating system installation task sequence. The Windows technology involved is called Features on Demand.

Default user settings

There are customizations that can be made to a Windows registry file called 'C:\Users\Default\NTUSER.DAT'. Any settings made to this file will be applied to any subsequent user profiles created from a device running this image. You can control which settings to apply to the default user profile, by editing the file 'DefaultUserSettings.txt'. One setting that you might want to consider carefully, new to this iteration of settings recommendations, is a setting called TaskbarSmallIcons. You might want to check with your user base before implementing this setting. TaskbarSmallIcons makes the Windows Task Bar smaller and consumes less screen space, makes the icons more compact, minimizes the Search interface, and is depicted before and after in the following illustrations:

Figure 1: Normal Windows 10, version 1909 taskbar

Figure 2: Taskbar using the small icons setting

Also, to reduce the transmitting of images over the VDI infrastructure, you can set the default background to a solid color instead of the default Windows 10 image. You can also set the logon screen to be a solid color, as well as turn off the opaque blurring effect on logon.

The following settings are applied to the default user profile registry hive, mainly in order to reduce animations. If some or all of these settings are not desired, delete the settings not to be applied to the new user profiles based on this image. The goal with these settings is to enable the following equivalent settings:

Figure 3: Optimized System Properties, Performance Options

For Windows 10, version 1909, the following are the optimization settings applied to the default user profile registry hive to optimize performance:

In the local policy settings, you might want to disable images for backgrounds in VDI. If you do want images, you might want to create custom background images at a reduced color depth to limit network bandwidth used for transmitting image information. If you decide to specify no background image in local policy, you might want to set the background color before setting local policy, because once the policy is set, the user has no way to change the background color. It might be better to specify "(null)" as the background image. There is another policy setting in the next section on not using background over Remote Desktop Protocol sessions.

Local policy settings

Many optimizations for Windows 10 in a VDI environment can be made using Windows policy. The settings listed in the table in this section can be applied locally to the base/gold image. If the equivalent settings are not specified in any other way, such as group policy, the settings would still apply.

Some decisions might be based on the specifics of the environment for example:

• Is the VDI environment allowed to access the Internet?

• Is the VDI solution persistent or non-persistent?

The following settings were chosen to not counter or conflict with any setting that has anything to do with security. These settings were chosen to remove settings or disable functionality that might not be applicable to VDI environments.

Policy Setting	Item	Sub-item	Possible setting and comments
Local Computer Policy \ Computer Configuration \ Windows Settings \ Security Settings
Network List Manager policies	All networks properties	Network location	User can't change location
Local Computer Policy \ Computer Configuration \ Administrative Templates \ Control Panel
*Control Panel	Allow online tips		Disabled. Settings won't contact Microsoft content services to retrieve tips and help content.
*Control Panel\Personalization	Won't show the Lock screen	Enabled. This setting controls whether the lock screen appears for users. If you enable this policy setting, users that are not required to press CTRL + ALT + DEL before signing in will see their selected tile after locking their PC.
*Control Panel\Personalization	Force a specific default lock screen and logon image		Enabled. This setting lets you specify the default lock screen and logon image shown when no user is signed in, and also sets the specified image as the default for all users--it replaces the default image. We recommend using a low resolution, non-complex image so less data is transmitted over the network each time the image is rendered.
*Control Panel\Regional and Language Options\Handwriting personalization	Turn off automatic learning		Enabled. If you enable this policy setting, automatic learning stops, and any stored data is deleted. Users can't configure this setting in Control Panel.
Local Computer Policy \ Computer Configuration \ Administrative Templates \ Network
Background Intelligent Transfer Service (BITS)	Do not allow the BITS client to use Windows Branch Cache		Enabled
Background Intelligent Transfer Service (BITS)	Do not allow the computer to act as a BITS Peercaching client		Enabled
Background Intelligent Transfer Service (BITS)	Do not allow the computer to act as a BITS Peercaching server		Enabled
Background Intelligent Transfer Service (BITS)	Allow BITS Peercaching		Disabled
BranchCache	Turn on BranchCache		Disabled
*Fonts	Enable font providers		Disabled. Windows doesn't connect to an online font provider and only enumerates locally-installed fonts.
Hotspot authentication	Enable hotspot authentication		Disabled
Microsoft Peer-to-Peer Networking Services	Turn off Microsoft Peer-to-Peer Networking Services		Enabled
Network connectivity status indicator	Specify passive polling.	Disable passive polling (check box)	Enabled. Use this setting if you're on an isolated network or using a static IP address.

Notes about Network Connectivity Status Indicator

The group policy settings above include settings to turn off checking to see if the system is connected to the Internet. If your environment does not connect to the Internet at all, or connects indirectly, you can set a group policy setting to remove the Network icon from the Taskbar. The reason you might want to remove the Network icon from the Taskbar is if you turn off Internet connectivity checks, there will be a yellow flag on the Network icon, even though the network might be functioning normally. If you would like to remove the network icon as a group policy setting, you can find that in this location:

Policy Setting	Item	Sub-item	Possible setting and comments
Windows Update or Windows Update for Business	Select when Quality Updates are received	1. 30 days 2. Pause quality updates starting yyyy-mm-dd	Enabled
Local Computer Policy \ User Configuration \ Administrative Templates
Start Menu and Taskbar	Remove the networking icon		Enabled. The networking icon isn't displayed in the system notification area.

For more information about the Network Connection Status Indicator (NCSI), see Manage connection endpoints for Windows 10 Enterprise, version 1903 and Manage connections from Windows 10 operating system components to Microsoft services.

System services

If you're considering disabling your system services to conserve resources, great care should be taken that the service being considered isn't in some way a component of some other service. Note that some services are not in the list because they can't be disabled in a supported manner.

Most of these recommendations mirror recommendations for Windows Server 2016, installed with the Desktop Experience in Guidance on disabling system services on Windows Server 2016 with Desktop Experience

Many services that might seem like good candidates to disable are set to manual service start type. This means that the service won't automatically start and isn't started unless a process or event triggers a request to the service being considered for disabling. Services that are already set to start type Manual are usually not listed here.

Note

You can enumerate running services with this PowerShell sample code, outputting only the service short name:

                          Get-Service | Where-Object {$_.Status -eq "Running"} | Select-Object -ExpandProperty Name                      

Windows Service	Item	Comments
CDPUserService	This user service is used for Connected Devices Platform scenarios	This is a per-user service, and as such, the template service must be disabled.
Connected User Experiences and Telemetry	Enables features that support in-application and connected user experiences. Additionally, this service manages the event-driven collection and transmission of diagnostic and usage information (used to improve the experience and quality of the Windows Platform) when the diagnostics and usage privacy option settings are enabled under Feedback and Diagnostics.	Consider disabling if on disconnected network.
Contact Data	Indexes contact data for fast contact searching. If you stop or disable this service, contacts might be missing from your search results.	This is a per-user service, and as such, the template service must be disabled.
Diagnostic Policy Service	Enables problem detection, troubleshooting and resolution for Windows components. If this service is stopped, diagnostics will no longer function.
Downloaded Maps Manager	Windows service for application access to downloaded maps. This service is started on-demand by application accessing downloaded maps. Disabling this service will prevent apps from accessing maps.
Geolocation Service	Monitors the current location of the system and manages geofences
GameDVR and Broadcast user service	This user service is used for Game Recordings and Live Broadcasts	This is a per-user service, and as such, the template service must be disabled.
MessagingService	Service supporting text messaging and related functionality.	This is a per-user service, and as such, the template service must be disabled.
Optimize drives	Helps the computer run more efficiently by optimizing files on storage drives.	VDI solutions do not normally benefit from disk optimization. These "drives" are not traditional drives and often just a temporary storage allocation.
Superfetch	Maintains and improves system performance over time.	Generally doesn't improve performance on VDI, especially non-persistent, given that the operating system state is discarded each reboot.
Touch Keyboard and Handwriting Panel Service	Enables Touch Keyboard and Handwriting Panel pen and ink functionality
Windows Error Reporting	Allows errors to be reported when programs stop working or responding and allows existing solutions to be delivered. Also allows logs to be generated for diagnostic and repair services. If this service is stopped, error reporting might not work correctly, and results of diagnostic services and repairs might not be displayed.	With VDI, diagnostics are often performed in an offline scenario, and not in mainstream production. And in addition, some customers disable WER anyway. WER incurs a tiny amount of resources for many different things, including failure to install a device, or failure to install an update.
Windows Media Player Network Sharing Service	Shares Windows Media Player libraries to other networked players and media devices using Universal Plug and Play	Not needed unless customers are sharing WMP libraries on the network.
Windows Mobile Hotspot Service	Provides the ability to share a cellular data connection with another device.
Windows Search	Provides content indexing, property caching, and search results for files, e-mail, and other content.	Probably not needed especially with non-persistent VDI

Per-user services in Windows

Per-user services are services that are created when a user signs into Windows or Windows Server and are stopped and deleted when that user signs out. These services run in the security context of the user account - this provides better resource management than the previous approach of running these kinds of services in Explorer, associated with a preconfigured account, or as tasks.

Per-user services in Windows 10 and Windows Server

If you intend to change a service start value, the preferred method is to open an elevated .cmd prompt and run the Service Control Manager tool 'Sc.exe'. For more information on using 'Sc.exe' see Sc.

Scheduled tasks

Like other items in Windows, ensure an item isn't needed before you consider disabling it.

The following list of tasks are those that perform optimizations or data collections on computers that maintain their state across reboots. When a VDI VM task reboots and discards all changes since last boot, optimizations intended for physical computers are not helpful.

You can get all the current scheduled tasks, including descriptions, with the following PowerShell code:

                          Get-ScheduledTask | Select-Object -Property TaskPath,TaskName,State,Description                      

Note

There are several tasks that can't be disabled via script, even if you're running elevated. We recommend that you don't disable tasks that can't be disabled using a script.

Apply Windows (and other) updates

Whether from Microsoft Update, or from your internal resources, apply the available updates including Windows Defender signatures. This is a good time to apply other available updates including Microsoft Office if installed, and other software updates. If PowerShell will remain in the image you can download the latest available help for PowerShell by running the command Update-Help.

Servicing the operating system and apps

At some point during the image optimization process available Windows updates should be applied. There is a setting in Windows 10 Update Settings that can provide additional updates:

This would be a good setting in case you are going to install Microsoft applications such as Microsoft Office to the base image. That way Office is up to date when the image is put in service. There are also .NET updates and certain third-party components such as Adobe that have updates available through Windows Update.

One very important consideration for non-persistent VDI VMs are security updates, including security software definition files. These updates might be released once or more than once per day. There might be a way to retain these updates, including Windows Defender and third-party components.

For Windows Defender it might be best to allow the updates to occur, even on non-persistent VDI. The updates are going to apply nearly every logon session, but the updates are small and should not be a problem. Additionally, the VM won't be behind on updates because only the latest available updates will apply. The same might be true for third-party definition files.

Note

Store apps (UWP apps) update through the Windows Store. Modern versions of Office such as Microsoft 365 update through their own mechanisms when directly connected to the Internet, or via management technologies when not.

Windows system startup event traces

Windows is configured, by default, to collect and save limited diagnostic data. The purpose is to enable diagnostics, or to record data if further troubleshooting is necessary. Automatic system traces can be found at the location shown in the following illustration:

Some of the traces displayed under Event Trace Sessions and Startup Event Trace Sessions can't and should not be stopped. Others, such as the 'WiFiSession' trace can be stopped. To stop a running trace under Event Trace Sessions right-click the trace and then click 'Stop'. Use the following procedure to prevent the traces from starting automatically on startup:

1. Click the Startup Event Trace Sessions folder.

2. Locate the trace of interest, and then double-click that trace.

3. Click the Trace Session tab.

4. Click the box labeled Enabled to remove the check mark.

5. Click Ok.

The following are some system traces to consider disabling for VDI use:

Name	Comment
AppModel	A collection of traces, one of which is phone
CloudExperienceHostOOBE
DiagLog
NtfsLog
TileStore
UBPM
WiFiDriverIHVSession	If not using a WiFi device
WiFiSession
WinPhoneCritical

Windows Defender optimization with VDI

Microsoft has recently published documentation regarding Windows Defender in a VDI environment. See Deployment guide for Windows Defender Antivirus in a virtual desktop infrastructure (VDI) environment for more information.

The above article contains procedures to service the 'gold' VDI image, and how to maintain the VDI clients as they are running. To reduce network bandwidth when VDI computers need to update their Windows Defender signatures, stagger reboots, and schedule reboots during off hours where possible. The Windows Defender signature updates can be contained internally on file shares, and where practical, have those files shares on the same or close networking segments as the VDI virtual machines.

Client network performance tuning by registry settings

There are some registry settings that can increase network performance. This is especially important in environments where the VDI or computer has a workload that is primarily network-based. The settings in this section are recommended to bias performance toward networking, by setting up additional buffering and caching of things like directory entries.

Note

Some settings in this section are registry-based only and should be incorporated in the base image before the image is deployed for production use.

The following settings are documented in the Windows Server 2016 Performance Tuning Guideline, published on Microsoft.com by the Windows Product Group.

DisableBandwidthThrottling

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\DisableBandwidthThrottling

Applies to Windows 10. The default is 0. By default, the SMB redirector throttles throughput across high-latency network connections, in some cases to avoid network-related timeouts. Setting this registry value to 1 disables this throttling, enabling higher file transfer throughput over high-latency network connections. Consider setting this value to 1.

FileInfoCacheEntriesMax

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\FileInfoCacheEntriesMax Applies to Windows 10. The default is 64, with a valid range of 1 to 65536. This value is used to determine the amount of file metadata that can be cached by the client. Increasing the value can reduce network traffic and increase performance when many files are accessed. Try increasing this value to 1024.

DirectoryCacheEntriesMax

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\DirectoryCacheEntriesMax

Applies to Windows 10. The default is 16, with a valid range of 1 to 4096. This value is used to determine the amount of directory information that can be cached by the client. Increasing the value can reduce network traffic and increase performance when large directories are accessed. Consider increasing this value to 1024.

FileNotFoundCacheEntriesMax

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\FileNotFoundCacheEntriesMax

Applies to Windows 10. The default is 128, with a valid range of 1 to 65536. This value is used to determine the amount of file name information that can be cached by the client. Increasing the value can reduce network traffic and increase performance when many file names are accessed. Consider increasing this value to 2048.

DormantFileLimit

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\DormantFileLimit

Applies to Windows 10. The default is 1023. This parameter specifies the maximum number of files that should be left open on a shared resource after the application has closed the file. Where many thousands of clients are connecting to SMB servers, consider reducing this value to 256.: Windows Server 2022, Windows Server 2019,

You can configure many of these SMB settings by using the Set-SmbClientConfiguration and Set-SmbServerConfiguration Windows PowerShell cmdlets. Registry-only settings can be configured by using Windows PowerShell as well, as in the following example:

            Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecuritySignature -Value 0 -Force                      

Additional settings from the Windows Restricted Traffic Limited Functionality Baseline guidance.

Microsoft has released a baseline, created using the same procedures as the Windows Security Baselines, for environments that are either not connected directly to the Internet, or wish to reduce data sent to Microsoft and other services.

The Windows Restricted Traffic Limited Functionality Baseline settings are called out in the group policy table with an asterisk.

Disk cleanup (including using the Disk Cleanup Wizard)

Disk cleanup can be especially helpful with gold/master image VDI implementations. After the image is prepared, updated, and configured, one of the last tasks to perform is disk cleanup. There is a built-in tool called the "Disk Cleanup Wizard" that can help clean up most potential areas of disk space savings. On a VM that has very little installed, but was fully patched you can usually get about 4GB disk space freed up running Disk Cleanup.

Here are suggestions for various disk cleanup tasks. These should all be tested before implementing:

1. Run (elevated) Disk Cleanup Wizard after applying all updates. Include the categories 'Delivery Optimization' and 'Windows Update Cleanup'. This process can be automated, using command line Cleanmgr.exe with the /SAGESET:11 option. The /SAGESET option sets registry values that can be used later to automate disk cleanup, that uses every available option in the Disk Cleanup Wizard.

   1. On a test VM, from a clean installation, running Cleanmgr.exe /SAGESET:11 reveals that there are only two automatic disk cleanup options enabled by default:

      • Downloaded Program Files

      • Temporary Internet Files

   2. If you set more options, or all options, those options are recorded in the registry, according to the Index value provided in the previous command (Cleanmgr.exe /SAGESET:11). In this case, we are going to use the value 11 as our index, for a subsequent automated disk cleanup procedure.

   3. After running Cleanmgr.exe /SAGESET:11 you'll see several categories of disk cleanup options. You can check every option, and then click OK. The Disk Cleanup Wizard disappears and your settings are saved in the registry.

2. Cleanup your Volume Shadow Copy storage, if any is in use.

   • Open an elevated command prompt and run the vssadmin list shadows command and then the vssadmin list shadowstorage command.

     If output from these commands is No items found that satisfy the query, then there is no VSS storage in use.

3. Cleanup temporary files and logs. From an elevated command prompt, run the Del C:\*.tmp /s command, the Del C:\Windows\Temp\. command, and the Del %temp%\. command.

4. Delete any unused profiles on the system by running, wmic path win32_UserProfile where LocalPath="c:\users\<user>" Delete.

Remove OneDrive Components

Removing OneDrive involves removing the package, uninstalling, and removing *.lnk files. The following sample PowerShell code can be used to assist in removing OneDrive from the image, and is included in the GitHub VDI optimization scripts:

            Get-Process -Name OneDrive | Stop-Process -Force -Confirm:$false Get-Process -Name explorer | Stop-Process -Force -Confirm:$false if (Test-Path "C:\\Windows\\System32\\OneDriveSetup.exe")`     { Start-Process "C:\\Windows\\System32\\OneDriveSetup.exe"`         -ArgumentList "/uninstall"`         -Wait } if (Test-Path "C:\\Windows\\SysWOW64\\OneDriveSetup.exe")`     { Start-Process "C:\\Windows\\SysWOW64\\OneDriveSetup.exe"`         -ArgumentList "/uninstall"`         -Wait } Remove-Item -Path "C:\\Windows\\ServiceProfiles\\LocalService\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\OneDrive.lnk" -Force Remove-Item -Path "C:\\Windows\\ServiceProfiles\\NetworkService\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\OneDrive.lnk" -Force  # Remove the automatic start item for OneDrive from the default user profile registry hive  Start-Process C:\\Windows\\System32\\Reg.exe -ArgumentList "Load HKLM\\Temp C:\\Users\\Default\\NTUSER.DAT" -Wait Start-Process C:\\Windows\\System32\\Reg.exe -ArgumentList "Delete HKLM\\Temp\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run /v OneDriveSetup /f" -Wait Start-Process C:\\Windows\\System32\\Reg.exe -ArgumentList "Unload HKLM\\Temp" -Wait Start-Process -FilePath C:\\Windows\\Explorer.exe -Wait                      

Turn Windows Update back on

If you would like to turn Windows Update back on, as in the case of persistent VDI, follow these steps:

• Re-enable these group policy settings:

  • Local Computer Policy \ Computer Configuration \ Administrative Templates \ System \ Internet Communication Management \ Internet Communication settings

    • Turn off access to all Windows Update features (change from enabled to not configured).

  • Local Computer Policy \ Computer Configuration \ Administrative Templates \ Windows Components \ Windows Update

    • Remove access to all Windows Update features (change from enabled to not configured)

    • Do not connect to any Windows Update Internet locations (change from enabled to not configured).

  • Local Computer Policy \ Computer Configuration \ Administrative Templates \ Windows Components \ Windows Update \ Windows Update for Business

    • Select when Quality Updates are received (change from 'enabled' to 'not configured')

  • Local Computer Policy \ Computer Configuration \ Administrative Templates \ Windows Components \ Windows Update \ Windows Update for Business

    • Select when Preview Builds and Feature Updates are received (change from enabled to not configured)

• Re-enable service(s)

  • Update the Orchestrator service (change from disabled to Automatic (Delayed Start)).

  • Edit the following Windows registry settings:

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UpdatePolicy\PolicyState

      • DeferQualityUpdates (change from 1 to 0)

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UpdatePolicy\Settings

      • PausedQualityDate (delete any existing value)

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\WAU

      • Disabled

• Re-enable scheduled tasks

  • Task Scheduler Library \ Microsoft \ Windows \ InstallService\ ScanForUpdates

  • Task Scheduler Library \ Microsoft \ Windows \ InstallService \ ScanForUpdatesAsUser

To make all these settings take effect, restart the device. If you don't want this device offered Feature Updates, go to Settings \ Windows Update \ Advanced options \ Choose when updates are installed, and then manually set the option, A feature update includes new capabilities and improvements. It can be deferred for this many days to some non-zero value, such as 180, 365, etc.
