Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This article helps you choose settings for Windows 10, version build 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. These recommended settings can be applied to other Windows 10 installations, including those on physical or other virtual machines. No recommendations in this article should affect supportability of Windows 10 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 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. 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.
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. This script was designed to suit your environment and requirements. 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. 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. 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. 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. 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. At some point updates must be applied to the master. This is where implementations decide how the user persistent changes are handled.
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.
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:. 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. Windows 10 performs a set of maintenance tasks, automatically, on a periodic basis.
There is a scheduled task that is set to run at 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:. One of the challenges with non-persistent VDI is that when a user logs off, nearly all the operating system activity is discarded. Therefore, optimizations intended for a Windows computer that saves state from one session to the next are not applicable.
Indexing might be a partial waste of resources, as would be any disk optimizations such as a traditional defragmentation.
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. 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. 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.
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. 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.
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.
