Cannot Disenroll from Windows 11 Insider Programme

[Ishan112c]

Hi Guys , 

Would really appreciate your help and support here . I enrolled myself into windows 11 Insider program and my system has been nothing but Shambles since then . Constant crashing , WIFI connectivity issues , lags , etc . Now that Im trying to disenroll , by clicking on " Leave the program" on the Insider website , I get told " This email address is not registered as a Windows Insider." .  

and Im not able to do this . Please help me get disenrolled from the insider program

@Ishan112c  Hi

If you manage to unregister, it will not remove the installed version of Insider.

You need to perform a clean installation of Windows10, or Windows11 - Which will clean everything and reinstall the system in the stable version
