Microsoft fixes issue preventing Windows logins

There is a bug in Windows 11 that prevents users from signing in after adding a new Microsoft account. According to Microsoft, this is caused by the KB5016691 update, which was rolled out in preview on August 25, 2022. The company quickly addressed the issue and provided detailed insights.

"After installing KB5016691 and adding a new Microsoft account user in Windows, you may be unable to log in for a short period of time after the first reboot or logout. The issue only affects newly added Microsoft account users, and only applies to first login ," Microsoft said.

Thankfully, Microsoft assured everyone affected that the issue will be resolved "in a short period of time." Additionally, it says it only concerns "newly added Microsoft account users, and only applies to first-time sign-in." Active Directory domain user accounts or Azure Active Directory accounts are also not affected by the bug, which is a relief.

To finally put an end to it, Microsoft has announced that it will release a known issue rollback, which should revert back to the buggy Windows fix that was rolled out earlier. No more than 24 hours, meaning issues with affected consumer and unmanaged business devices should be resolved by the weekend. Microsoft also recommends restarting your machine to help with the solution that is now being pushed.

For enterprise-managed devices, IT administrators should use KIR Group Policy to address this issue. "Special Group Policy can be found in Computer Configuration -> Administrative Templates -> KB5016691 220722_051525 Known Issues Rollback -> Windows 11 (original)," Microsoft explained, offering a Rollback Group Policy for Windows 11 V 21H2 link to download. The company also provided a support document detailing how to use Group Policy to deploy known issue rollbacks.
