Switching from Win 11 insider preview to general release

[Andris770]

I am currently trying to switch from the insider preview of Win 11 to the general release one. I have tried downloading the windows 11 installation assistant however when I try and run it a small blank window pops up and disappears after 1 second. The installation assistant never ends up running and every update I receive from the windows setting update menu is an insider preview one. I don't want to perform a clean install as I have files that are not backed up. If anyone has experienced this or has a way of switching from the insider preview I would really appreciate the help.

If you're currently running Win11 Insider Preview Build with Dev Channel then must back up your data to perform clean installation, there no way to perform an In-place upgrade. Personally I do the same and I wish MS could provide a tools for us but that's the case here.

Yes only removing and formatting the disk and then installing a lower version is possible - Dev versions. they do not have a full environment.
