I was in the Dev Channel and got Windows 11 updates. Then I used the script to move to the Beta channel. After Parallels 17 was released and advertised as being compatible with Windows 11, I used the script to leave the Insider Program. I then used the normal Windows settings to get back into the program and could only join the Release Preview Channel because Parallels 17 isn't actually compatible with Windows 11.
I haven't updated to 22000.176 yet, but I expect to get the update.
I'm pretty sure everyone who is already using Windows 11 will continue to get the cumulative 22000.xxx updates, but no more major (22xxx.xxx) updates.
