Can't go from Windows 11 dev channel to release version

FeelLikePhil It is possible to start Regedit, go to 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\UI\Selection' and change the option 'UIBranch' to another value. For instance, switch from 'Dev' to 'ReleasePreview'. However, I'm sure this is not officially supported and doing so can bring some unexpected results. In other words, Microsoft seems to protect you from getting into trouble.

As far as I know, the option is only greyed out when you've selected 'Dev' earlier. There is no option to switch to maintain continuity. Since the ‘Dev’ channel gets the latest features ahead of the other two channels, Windows does not have the necessary tools to carry out the swift onboarding process. To move from one channel to another, the build of the destination channel has to be newer than the channel you are currently on. I'm afraid a clean install will be your best option.
