Windows update KB5016691 push since the end of August 2022 has proved problematic. Adding a new Microsoft account user on Windows causes login issues.
Microsoft’s KB5016691 update for Windows launched on August 25 fixes many bugs. This is not a security patch for Windows 11 version 21H2 users, but it fixes many issues related to Windows services and features. Namely, problems related to USB printing, app approval from the publisher’s store, disconnection on Bluetooth audio headsets, as well as the Edge browser.
Only then did installing this update cause secondary damage. “After installing KB5016691 and adding a new user with a Microsoft account in Windows, you may be unable to sign in for a short time after the first reboot or sign out,” Microsoft explained. “The issue only affects the newly added Microsoft account user and only for the first login.” Note that this issue does not affect Active Directory domain user accounts or Azure Active Directory accounts.
A decision based on KIR
Two types of incident resolution are offered. One is “natural” as it resolves itself after a short time, namely waiting for the lock screen to reappear and then being able to log in normally. The other relies on help from Known Issues Restore (KIR). “Please note that it may take up to 24 hours for the resolution to automatically propagate to unmanaged consumer and business endpoints.” “Restarting your Windows device may help resolve the issue. For enterprise-managed devices that have installed an affected update and are experiencing this issue, you can resolve it by installing and configuring a special Group Policy. The special Group Policy is located in Computer Configuration – > Administrative Templates -> KB5016691 220722_051525 Known issue with rollback -> Windows 11 (original version),” Microsoft said.
