Microsoft urgently deploys a patch for Windows Login

Windows update KB5016691 pushes since late August 2022 is proving problematic. Adding a new Microsoft account user on Windows causes sign-in issues.

Microsoft’s KB5016691 update for Windows launched on August 25 corrects many malfunctions. This is not a security patch for Windows 11 version 21H2 users, but it addresses many issues related to Windows services and features. Namely problems related to USB printing, approval of applications from the publisher’s store, interruption on Bluetooth audio headsets as well as the Edge browser.

Only then, the installation of this update caused collateral damage. “After installing KB5016691 and adding a new user with a Microsoft account in Windows, you may not be able 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 sign-in.” Note that this issue does not affect Active Directory domain user accounts or Azure Active Directory accounts.

A resolution based on KIR

Two types of incident resolution are offered. One is “natural” since it resolves itself after a short period of time, namely waiting for the lock screen to reappear and then being able to log in normally. The second relies on the help of 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 devices,” says the publisher. “Restarting your Windows device may help resolve. For corporate-managed devices that have installed an affected update and experienced this issue, you can resolve it by installing and configuring a special Group Policy. Special Group Policy can be found in Computer Configuration -> Administrative Templates -> KB5016691 220722_051525 Known Rollback Issue -> Windows 11 (original release),” Microsoft said.
