The Windows update KB5016691 released at the end of August 2022 proved to be problematic. Adding a new Microsoft account user to Windows causes sign-in issues.
Microsoft update KB5016691 for Windows released on August 25 fixes many bugs. This is not a security patch for users of Windows 11 version 21H2, but it fixes many issues related to Windows services and features. Specifically, issues related to USB printing, app approval from the publisher’s store, interruptions to the Bluetooth audio headset, and the Edge browser.
Only then did installing this update cause collateral damage. “After installing KB5016691 and adding a new user with a Microsoft account to Windows, you won’t 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 on first login.” Note that this issue does not affect Active Directory domain user accounts or Azure Active Directory accounts.
Resolution based on KIR
Two types of incident resolution are offered. One of them is “natural” in that it resolves on its own after a short amount of time, namely waiting for the lock screen to reappear and then being able to log in normally. The second relies on Known Issue Recovery (KIR) assistance. “Please note that it may take up to 24 hours for the solution to be automatically distributed to unmanaged consumer and business devices,” says the publisher. “Rebooting your Windows device may help resolve the issue. For enterprise-owned devices that have the affected update installed and experience this issue, you can resolve the issue by installing and configuring a custom Group Policy. The specific Group Policy can be found under Computer Configuration -> Administrative Templates -> KB5016691 220722_051525 “Known Rollback Issue” -> “Windows 11 (Original Release)”, according to Microsoft.
