Microsoft released a patch to fix the problem that is preventing its users from logging into their Windows accounts.
Numerous Windows users experienced difficulties in creating a new Microsoft user account on their systems.
The users complained that after logging off or restarting a system that is running Windows 11, version 21H2, customers are unable to sign in back into newly added Microsoft Accounts.
Immediately following the initial restart or logout, users were unable to sign in for a short period of time. This problem only arises for users who have recently added a Microsoft account, and it occurs during the very first sign-in attempt.
According to BleepingComputer, the problem was due to a previous Windows 11 update in August, KB5016691.
Microsoft Fix Known Issue Rollback
Microsoft is addressing the Windows update problem by releasing a fix called the Known Issue Rollback (KIR).
The Known Issue Rollback is a significant Windows service feature that supports the fixing of non-security bugs created by the company.
It gives Microsoft the ability to rapidly roll back a single, targeted patch to a behavior that was previously released in the event that a major problem is detected in that patch.
It is a new tool that has the potential to quickly bring an impacted device back to productive use if an issue arises while a Windows update is being installed.
When KIR is deployed, Microsoft says that it could take as long as 24 hours for the fix to automatically disseminate to users and other non-managed business devices.
Users that run across this problem will not have to worry about it for very long because it will fix itself within a short while. Users will be required to wait for the lock screen to reappear before they are able to successfully log in, as was originally intended.
Additionally, Microsoft recommends to its users that they restart their devices in order to increase the likelihood that the fix will take effect on their devices more quickly.
According to Microsoft, "For enterprise-managed devices that have installed an affected update and encountered this issue can resolve it by installing and configuring a special Group Policy."
To access the special Group Policy, go to the Group Configuration, then select Administrative Templates, click on the KB5016691 220722_051525 Known Issue Rollback text option, then click Windows 11 (original release).

Microsoft's Windows Update KB5016691
Microsoft's Windows update that brought this issue to its consumers is KB5016691, which was released last month on August 25.
Despite the update triggering an unwanted inconvenience to users, the KB5016691 update brought numerous additional fixes to Windows and addressed pre-existing malfunctions that needed fixing.
As reported by Microsoft, the Windows update KB5016691 resolves a problem that, in its current state, prevents Windows 11 SE from trusting certain applications from the Microsoft Store.
Additionally, it resolves a problem regarding USB printing that, after users restart their printers or reinstall them, causes the printers to behave improperly. Also, it fixes a problem that could lead certain Bluetooth audio headphones to stop playing after an alteration is made to the progress bar.
Another new feature that was introduced by the Windows update was an improvement made in the capability of Microsoft Defender for Endpoint to recognize and prevent ransomware and sophisticated cyberattacks.
To access Windows Update, navigate to Settings, then find Update & Security and click it, then select Update.
