You need to do a clean install of Windows 11 to revert to the standard channel. There is no other way. Ideally you need to set up your system so that the Windows C drive contains just the OS, and all your data is on a separate drive or partition. Then the re-install just replaces the OS.
Okay so what if I get a new drive specifically for the OS, download the production version of Windows 11 onto that, and make it my boot drive. Will my apps and files on my previous C drive still be usable?
Sorry to bring back the dead but I have returned to the idea of leaving the dev channel. So will data that is not on my boot drive also be unrecoverable? Or can I save all my data to a secondary drive and reinstall, and have it be as I left it?
I hadn't noticed this thread [not following as I had left Win10 IP just as Win11 came out] but saw on the News widget a couple days ago that the IP is changing and apparently will require some reinstalling.
But as to user data, it was warned when I got into the Win10 IP not to use it on the only computer or a production computer so it was stressed for users to make backup copies of anything they didn't want to lose.
