Not so long ago, Microsoft provided detailed information about a neat feature called "Known Issue Rollback" or KIR. This tool helps Microsoft prevent widespread stability issues and bugs hitting more than 1.3 billion devices running Windows 10.
In a nutshell, when the user updates its computer and installs monthly patches or other types of updates, Windows keeps the old code as a backup for an emergency. Known Issue Rollback works seamlessly and quietly, and it does not require any actions from the user side. It has already proved its effectiveness in a number of cases. Recently, Microsoft used KIR to fix performance issues in games after rolling out another monthly update. Still, Known Issue Rollback has one questionable disadvantage.
Known Issue Rollback depends on Experimentation settings
As Microsoft started using Known Issue Rollback more actively, users noticed that KIR depends on their privacy preferences. To be precise, it requires turning on a feature called Experimentation. Experimentation is a policy Microsoft uses to remotely change some settings in your computer. Some users consider this a privacy invasion and use registry tweaks or third-party tools to disable Windows Experimentation. When you turn off the AllowExperimentation key in Windows Registry, Known Issue Rollback stops working.
The good thing is that you can bypass KIR dependency by temporarily enabling Windows Experiments. That will give your computer a chance to apply available fixes and get rid of the problem. Later, you can turn Experiments back off to if you believe that this will enhance your privacy and prevent Microsoft from collecting extra data on your device.
Enable Experimentation in Windows 10
To enable Experimentation in Windows 10, open Registry Editor and go to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\System. Find the
AllowExperimentation parameter and change its value to 1. After applying the available patches using KIR, you can change the parameter back to 0 or refer to the app that helps you manage privacy options not available by default in Windows Settings.
