Details:
A new resource is available to help you understand Known Issue Rollback (KIR). This well-established process automatically rolls back problematic code for a known issue in Windows non-security updates. This rollback applies automatically through Windows Update on non-IT-managed devices. IT-managed devices require a specific Group Policy configuration.
When will this happen:
KIR came together as a functionally complete system beginning in Windows 10, version 2004. Since then, most of the code changes in Windows monthly updates support KIR capability.
The new resource is now available to learn more about KIR.
