So far my son and I have done 5 “test” upgrades to Win 11, only 1 of them worked.
My main PC, his and his partners gaming PC’s and gaming laptop all failed and reverted back to 10. The only thing that it worked on was my new laptop which has very little on it apart from Windows itself.
Clean installs on all 5 worked perfectly, the only real annoyance is the insistence to have a Microsoft account and an Internet connection to be able to install it. There was a “secret” way to opt out on the trial version but that no longer works.
My laptop (which I hadn’t set up a Microsoft account for upgraded OK without being asked for one.
Will we be switching to it any time soon? short answer is no. I’ve left it on my laptop as it hardly ever gets used just to see how it runs.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
