Windows 11

Those Windows 11 users who got their hands on the KB5016691 update are now facing trouble signing up on their Microsoft accounts on their machines.

The culprit is the KB5016691 update that was rolled out on August 25, and it appears as if Microsoft is already releasing the patch update for the issue using the KIR method. Here’s more about it.

According to the latest update, the KB5016691 on Windows 11 21H2 prevented users from adding their newly created Microsoft Account. They could not properly log in immediately after adding the new account and restarting or signing out for the first time.

Note that the issue affects Microsoft accounts for the first sign-in only. Additionally, the bug doesn’t affect both Azure Active Directory Accounts and Active Directory Domain users’ accounts.

As of now, Microsoft has acknowledged the issue by blocking the KB5016691 update. It has revealed more information via the Known Issue Rollback (KIR) that allows the tech giant to release non-security fixes on consumer and non-managed business machines in a day instead of waiting for its rollout in phases part of regular rollouts.

Ideally, the update doesn’t take more than 24 hours, so those affected machines should get their hands on the update.

If you are an IT admin, you must install KIR Group Policy to resolve this Windows account login issue on enterprise-managed devices. Once you have installed, go to Computer Configuration >> Administrative Templates >> KB5016691 220722_051525 Known Issue Rollback >> Windows 11 (original release).

You can follow this support document published by Microsoft on how you can use Group Policy to apply KIR updates. A similar update was released in July 2022 when the tech giant released an emergency KIR update to address the Windows 11 start menu malfunction issue after installing recent updates.
