If you’re having issues since updating Windows 11 with the latest cumulative updates, you’re not alone. Although Windows 11 version 22H2 is around the corner and still in development compared to version 21H2, you may still experience issues on the production device.
At this point, most issues with Windows 11 version 21H2 have been resolved, but a few issues still appear in cumulative updates. Windows 11 KB5016691, the most recent update, can break desktop login and prevent users from accessing their devices.
In a new update of the support document, Microsoft has quietly confirmed that devices that rely on a Microsoft account to sign in may experience sign-in issues. This bug affects devices that have a new Microsoft account added. Users are unable to log in for a short time and this usually happens when you reboot or log out of the system.
This bug only affects devices with Microsoft accounts (persona or business) and does not affect companies using Active Directory domain accounts or Azure Active Directory accounts.
To fix sign-in issues, all you need to do is wait a few minutes. When you idle the machine and the lock screen appears, you should be able to log in as expected.
Microsoft has also started rolling out an emergency patch to fix these login issues on Windows 11. It may take up to 24 hours for the server-side update to be automatically distributed to consumer devices, but you can always reboot your system multiple times to quickly apply the hotfix.
Another known issue affects XPS Viewer, where the app cannot open XML Paper Specification (XPS) documents in some non-English languages. This includes Japanese and Chinese character encodings. Microsoft says the issue is noticeable in both XML Paper Specification (XPS) and Open XML Paper Specification (OXPS) files.
However, it will not affect most home users as the feature itself is installed longer by default.
