A bug may prevent you from signing in to Windows 11

Microsoft has confirmed one more bug in Windows 11. It affects the stable version of the OS, and may prevent the user from signing in to a newly added Microsoft Account. Fortunately, the company already mitigated the issue.

Windows 11 Sign In Screen

The description on the Windows Health Dashboard website says that the user couldn't sign in to Windows right after adding a new Microsoft Account in Settings > Accounts. It was required to wait for some short period of time before the operating system would allow the new credentials.


The problem is specific for personal accounts. Customers using the Active Directory based services aren't affected.

As follows from the statement, the bug was first introduced with KB5016691.

After installing KB5016691 and adding a new Microsoft account user in Windows, you might be unable to sign in for a brief time after the first restart or sign out. The issue only affects the newly added Microsoft account user and only for the first sign in.

Microsoft has applied the known issue rollback technology to mitigate the bug. If you are affected, you can now simply restart the operating system to make it apply the solution faster.

There is also a special Group Policy can be found in Computer Configuration -> Administrative Templates -> KB5016691 220722_051525 Known Issue Rollback -> Windows 11 (original release). It can speed up the device configuration if it doesn't receive the mitigation update. You can download the group policy package here.

Known Issue Rollback is a mechanism that Microsoft is using since Windows 10. It prevents the OS from using the newer code that is known to be buggy. Once applied, it switches Windows back to the older working piece of software. You can learn more about the Known Issue Rollback here.
