Windows 11 servicing stack update - 22000.1811

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.
All users	After installing this or later updates, Red Dead Redemption 2 might not open. When attempting to open it from the Rockstar Games Launcher by selecting the "Play" button, it will switch to "Loading", but Red Dead Redemption 2 might not open, and the button will revert to "Play".	This issue was resolved in an update from Rockstar Games for Red Dead Redemption 2. After updating to the latest version of the game, you should be able to open it as expected.
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.	To mitigate the issue, you can attempt to save or copy again. Since the issue is intermittent, it is likely to succeed on a subsequent try. Important If the resolution below does not resolve intermittent save or copy issues in your environment, then you might be experiencing a different issue with similar symptoms. This issue is resolved using Known Issue Rollback (KIR). Enterprise-managed devices that have installed an affected update and have encountered this issue can resolve it by installing and configuring a special Group Policy. The special Group Policy can be found in Computer Configuration -> Administrative Templates-> <Group Policy name listed below>. For information on deploying and configuring these special Group Policy, please seeHow to use Group Policy to deploy a Known Issue Rollback. Group Policy downloads with Group Policy name: Download for Windows 11, version 21H2 - KB5023774 230222_032017 Known Issue Rollback Important You will need to install and configure the Group Policy for your version of Windows to resolve this issue.
