Symptom

Using provisioning packages on Windows 11, version 22H2 (also called Windows 11 2022 Update) might not work as expected. Windows might only be partially configured, and the Out Of Box Experience might not finish or might restart unexpectedly. Provisioning packages are .PPKG files which are used to help configure new devices for use on business or school networks. Provisioning packages which are applied during initial setup are most likely to be impacted by this issue. For more information on provisioning packages, please see Provisioning packages for Windows.

Note Provisioning Windows devices using Windows Autopilot is not affected by this issue.

Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.

Workaround

If you can provision the Windows device before upgrading to Windows 11, version 22H2, this will prevent the issue.

We are presently investigating and will provide an update in an upcoming release.

Symptom

You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share via Server Message Block (SMB) but local file copy might also be affected.Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.

Workaround

To mitigate this issue, you can use file copy tools that do not use cache manager (buffered I/O). This can be done by using the built-in command-line tools listed below:

robocopy \\someserver\someshare c:\somefolder somefile.img /J

or

xcopy \\someserver\someshare c:\somefolder /J

We are working on a resolution and will provide an update in an upcoming release.
