This capability will only apply to non-security bug fixes and will help you revert a single fix to a previously released state. Microsoft officials wrote in a blog post that the Known Issue Rollback feature was fully functional even beginning with Windows 10, version 2004. Since then, they released monthly updates with some of the quality changes protected by the Known Issue Rollback capability.
What is Known Issue Rollback and what versions does it cover?
From the Microsoft blog post we found out that Known Issue Rollback was designed for user-mode processes, but it gradually improved to cover the kernel mode. Although this capability originates from version 2004, older versions like 1909 and 1809 also have partial support for KIR built into the OS. So, KIR is actually a quicker way of fixing the non-security updates bugs. When there is a known issue with a bug fix in an update, Microsoft can make a configuration change in the cloud. And if your device is connected to the Windows Update or Windows Update for Business services, you will be notified about this change and after a reboot, the changes will take effect. Microsoft is explaining what happens next with your system: The Microsoft officials say that the rollback is so effective that most users won’t even notice it: From this point on, the OS will fall back to the previous code that had a bug albeit a much more benign issue than the new code that has a problem. It sounds like the new KIR capability will change the bug fixing dynamics for Windows 10 updates. What are your thoughts about this new feature? Let us know about it in the comments section below.
