The second set of instructions there ("How to Create a Windows 11 Install Disk that Allows Bypassing Microsoft Accounts") seem non-cryptic and fairly approachable for anyone who can create USB install media.

I haven't tried it myself, I'm trialling an "upgrade" to Pop OS rather than Win11. So far so good, full credit to System76 for the progress they've made a in a few years. I'd consider buying one of their systems if they handled tax + duty for international shipping - insanity can ensure in the UK for packages that arrive without it all arranged.

Slightly more on topic, I've never trusted Apple.
