Windows 10 September Update Causes Multiple Built-in Apps to Fail, Microsoft Releases Fix

Microsoft has revealed in its Health Dashboard that following the installation of the September 2024 Preview Update KB5043131 for Windows 11 version 22H2 (Final version), and subsequent cumulative updates, some system built-in applications fail to launch properly.

This issue is likely to predominantly affect enterprise and educational users since it only occurs when users attempt to start these applications using non-administrator accounts, whereas personal and family users typically operate under administrator accounts.

Affected applications include built-in features like Quick Assist, Microsoft Teams, and Windows Narrator. In fact, any application set with the UIAccess attribute to True fails to launch from non-admin profiles.

To mitigate this, Microsoft has implemented a Known Issue Rollback (KIR) via backend server configurations. Systems connected to the internet should automatically receive the fix within about 24 hours.

Users can also directly reboot their systems while connected to the internet to force the receipt of the latest server-side updates to address this issue, thus restoring functionality after the restart.

Microsoft has not disclosed the root cause of this issue but has promised a thorough fix in a future cumulative update, which will resolve the issue regardless of server-side update acceptance.

For managed devices within enterprises and educational institutions, IT administrators must employ specific strategies to revoke changes causing app incompatibility with the latest updates. For strategy download, click here.
