Windows 11 servicing stack update - 22000.378
This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.
Known issues in this update
| Applies to | Symptom | Workaround |
|---|
| IT admins | 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. |
| IT admins | 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. |
| All users | On October 5, 2022, the Jordanian government made an official announcement ending the winter-time Daylight Saving Time (DST) time zone change. Starting at 12:00 a.m. Friday, October 28, 2022, the official time will not advance by an hour and will permanently shift to the UTC + 3 time zone.
The impact of this change is as follows:
- Clocks will not be advanced by an hour at 12:00 a.m. on October 28, 2022 for the Jordan time zone.
- The Jordan time zone will permanently shift to the UTC + 3 time zone.
Symptoms if no update is installed and the workaround is not used on devices in the Jordan time zone on October 28, 2022 or later:
- Time shown in Windows and apps will not be correct.
- Apps and cloud services which use date and time for integral functions, such as Microsoft Teams and Microsoft Outlook, notifications and scheduling of meetings might be 60 minutes off.
- Automation using date and time, such as Scheduled tasks, might not run at the expected time.
- Timestamp on transactions, files, and logs will be 60 minutes off.
- Operations that rely on time-dependent protocols such as Kerberos might cause authentication failures when attempting to logon or access resources.
- Windows devices and apps outside of Jordan might also be affected if they are connecting to servers or devices in Jordan or if they are scheduling or attending meetings taking place in Jordan from another location or time zone. Windows devices outside of Jordan should not use the workaround, as it would change their local time on the device.
| This issue is addressed in KB5018496. This update will not install automatically. To apply this update, you can check for updates and select the optional preview to download and install.
If you cannot install this update, you can mitigate this issue on devices in Jordan by doing either of the following on October 28, 2022:
- Select the Windows logo key, type "Date and time", and select Date and time settings. From the Date & time settings page, toggle Adjust for daylight saving time automatically to Off.
- Go to Control Panel > Clock and Region > Date and Time > Change time zone and uncheck the option for “Automatically adjust clock for Daylight Saving Time”.
Important: We recommend using ONLY the above workaround to mitigate the issue with time created by the new Daylight Savings Time in Jordan. We do NOT recommend using any other workaround, as they can create inconsistent results and might create serious issues if done incorrectly. |
| IT admins | After this and later updates are installed, domain join operations might be unsuccessful and error "0xaac (2732): NERR_AccountReuseBlockedByPolicy" occurs. Additionally, text stating "An account with the same name exists in Active Directory. Re-using the account was blocked by security policy" might be displayed.
Affected scenarios include some domain join or re-imaging operations where a computer account was created or pre-staged by a different identity than the identity used to join or re-join the computer to the domain.
For more information about this issue, see KB5020276 - Netjoin: Domain join hardening changes.
Note Consumer Desktop editions of Windows are unlikely to experience this issue. | We have added guidance to KB5020276 and are evaluating whether optimizations can be made in a future Windows Update. This guidance will be updated as soon as those changes are released. |
