Windows 11 servicing stack update - 22621.1771

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.

Applies to Symptom Workaround
IT admins You might have intermittent issues saving, copying, or attaching files using 32-bit apps, which are large address aware and using the CopyFile API. Windows devices are more likely to be affected by this issue when using some commercial or enterprise security software that uses extended file attributes. Microsoft Office apps, such as Microsoft Word or Microsoft Excel are only affected when using 32-bit versions and you might receive the error, "Document not saved." This issue is unlikely to be experienced by consumers using Windows devices in their home or on non-managed commercial devices. Apps are not affected by this issue if they are 64-bit or 32-bit and NOT large address aware. This issue is addressed in KB5027231.

How to get this update

Before installing this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Install this update

Release Channel Available Next Step
Windows Update or Microsoft Update Yes Go to Settings > Update & Security > Windows Update. In the Optional updates available area, you’ll find the link to download and install the update.
Windows Update for Business No None. These changes will be included in the next security update to this channel.
Microsoft Update Catalog Yes To get the standalone package for this update, go to the Microsoft Update Catalog website.
Windows Server Update Services (WSUS) No You can import this update into WSUS manually. See the Microsoft Update Catalog for instructions.

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.
