Optimizing images has always been an important component of preparing images as part of a traditional Remote Desktop Services (RDS) infrastructure or virtual desktop infrastructure (VDI). Optimizing session hosts, in particular, can increase user density and eventually lower costs.
With the Virtual Desktop Optimization Tool, you can optimize your Windows 10, version 2004 multi- and single-session deployments in Windows Virtual Desktop.
Note: The information in this post is community-driven; nothing has yet been officially launched by the Windows Virtual Desktop product team. Credit goes to Robert M. Smith and Tim Muessig from Microsoft, previously known as the VDIGuys, for creating this tool and make it available for free for the community.
Windows 10 multi-session image name change
As noted in recent announcements, Office 365 ProPlus is now Microsoft 365 apps for Enterprise. With this name change, we have updated the Windows Virtual Desktop image names in Azure Marketplace. As a result, when you are looking for an image in the Azure Marketplace image gallery, you should begin by selecting Windows 10 Enterprise multi-session, version 2004 + Microsoft 365 Apps – Gen1 as your baseline image
How the Virtual Desktop Optimization Tool works
The (Windows) Virtual Desktop Optimization Tool disables services in the operating system that you most likely won’t need for your Windows Virtual Desktop session host. To make sure that your line-of-business (LOB) applications continue running as they should, there are some preliminary steps that should first performed.
The full list of enhancements for native Windows services will be available soon. Bookmark Run and tune your Remote Desktop Services environment for the latest updates.
Expected performance gains
Windows Virtual Desktop value-added services provider and Microsoft partner LoginVSI performed early tests with the Virtual Desktop Optimization Too and gained over 100 users in their internal benchmarking lab environment with a Windows 10, version 2004 single session. We, therefore, assume that this gain will also be possible with Windows 10 Enterprise multi-session.
VSImax asserts a maximum number of users that are able to log on to the virtual desktop hosts pool as part of the underlying infrastructure. That number is the “sweet spot” as going over that number will decrease performance for all users. (Thanks to LoginVSI for sharing these results with us.)
Note: We recommend you use simulation tools to test your deployment using both stress tests and real-life usage simulations to ensure that your system is responsive and resilient enough to meet user needs Remember to vary the load size to avoid surprises.
How the Virtual Desktop Optimization Tool works
The Virtual Desktop Optimization Tool makes it possible to disable uncommon services for virtual desktop environments, such as Windows Virtual Desktop.
Note: We recommend that you run the script after the Sysprep (System Preparation) process, most likely as startup script w with a large set of virtual machines.
Download all the scripts from the public Github repository below –
Click on Clone or Download followed by Download ZIP.
Unzip the folder to your Windows Virtual Desktop – session host(s) – in a random folder (ex. C:Optimize or C:Temp).
Note: You could also run the scripts as part of your image management procedure e.g. Azure image Builder (AIB) or Azure DevOps if you like.
Start PowerShell – Run as Administrator
In PowerShell, change directory to the scripts folder (e.g. C:Optimize or your own specific folder)
Run the following command to make running possible
Set-ExecutionPolicy -ExecutionPolicy Bypass
Run the VirtualDesktopOptimizationTool steps – by running the command below.
.Win10_VirtualDesktop_Optimize.ps1 -WindowsVersion 2004 -Verbose
Note: When you use a different build of Windows 10, you must change the WindowsVersion parameter. Build 1803 and up are supported as well for Windows 10 Enterprise. Windows 10 multi-session support applies only to build 2004.
When complete, you should see a prompt to restart.
Reboot the session hosts(s)
Start your Windows Virtual Desktop session
Results out of the performance improvements. As you can see, the number of threads and handles decrease a lot.
