Microsoft has acknowledged a new issue preventing some Windows apps to open after an update or repair attempt. The bug has been discovered following the release of November Patch Tuesday updates last week, and it currently affects Windows 11 as well as the latest versions of Windows 10, including the just-released version 21H2.
According to the Windows Health dashboard (via Bleeping Computer), "Microsoft Installer (MSI) might have issues repairing or updating apps. Apps that are known to be affected include some apps from Kaspersky. Affected apps might fail to open after an update or repair has been attempted,” the company explained.
While Microsoft is currently working on a fix, the company recommends users unable to open Windows apps to uninstall and reinstall them. Except for the Kasperky apps that the company mentioned on the Windows Health Dashboard, it's not clear if this Microsoft Installer issue is breaking many other Windows apps.
If you're running Windows 11 on your PC, the company has also acknowledged a new compatibility issue with Intel SST drivers earlier this week. With some Windows 11 users seeing BSOD errors when using the affected drivers, Microsoft has put an upgrade block in place for Windows 10 users until this issue has been resolved.
