## What you need to know

Which configuration layer should hold an optimization for a nonpersistent VDI desktop?

## Potentially affected

Use this review when planning changes to a VDI image.

## DSE recommendation

Create an image change record that names the user experience being improved and the setting being changed.

## Article

## Source facts

Microsoft distinguishes persistent, nonpersistent, and session-based virtual desktop implementations. Some implementations deliver desktops derived from a shared base operating-system image. For nonpersistent desktops built from a gold image, Microsoft places most optimization work in that image, supplemented by local settings and policies. Microsoft identifies Sysprep as the tool for preparing a customized Windows 10 or Windows 11 image for duplication. [Microsoft documentation](https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/remote-desktop-services-vdi-optimize-configuration).

## Applicability

Use this review when planning changes to a VDI image. Identify the desktop model, image owner, provisioning method, and policy layers. Check the source sections applicable to that model before applying an optimization list.

## DSE recommendation

Create an image change record that names the user experience being improved and the setting being changed. Test one focused group of settings at a time. Include the desktop team and the owners of essential applications in acceptance criteria. Keep the previous image available through the approved image-management process and specify how a failed pilot will return to it.

## Verification

Test a freshly provisioned desktop and a subsequent user session. Record application behavior, sign-in experience, and whether the intended settings remain where expected after reprovisioning. Include representative user tasks, not only an idle desktop observation. Document each accepted setting and any exception before updating the broader image population.
