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.
|
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.

Copying large multiple gigabyte (GB) files might take longer than expected to finish on Windows 11, version 22H2. 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.
|
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.

After you install this or later updates, you might be unable to reconnect to Direct Access after temporarily losing network connectivity or transitioning between Wi-Fi networks or access points.
Note This issue should not affect other remote access solutions such as VPN (sometimes called Remote Access Server or RAS) and Always On VPN (AOVPN).
Windows devices used at home by consumers or devices in organizations which are not using Direct Access to remotely access the organization's network resources are not affected.
|
If you cannot use the resolution below, you can mitigate this issue by restarting your Windows device.
This issue is resolved using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices. Restarting your Windows device might help the resolution apply to your device faster. For enterprise-managed devices that have installed an affected update and encountered this issue can be resolved by installing and configuring a special Group Policy. The special Group Policy can be found in Computer Configuration -> Administrative Templates ->
For information on deploying and configuring these special Group Policy, please see How to use Group Policy to deploy a Known Issue Rollback.
