Windows 11 servicing stack update – 22000.1879
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 |
|---|---|---|
| All users | After installing this or later updates, Windows devices with some third-party UI customization apps might not start up. These third-party apps might cause errors with explorer.exe that might repeat multiple times in a loop. The known affected third-party UI customization apps are ExplorerPatcher and StartAllBack. These types of apps often use unsupported methods to achieve their customization and as a result can have unintended results on your Windows device.
|
We recommend uninstalling any third-party UI customization app before installing this or later updates to prevent this issue. If your Windows device is already experiencing this issue, you might need to contact customer support for the developer of the app you are using. If you are using StartAllBack, you might be able to prevent this issue by updating to the latest version (v3.5.6 or later).
We are presently investigating and will provide more information when it is available.

If you want to remove the LCU
To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.
Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
