I haven't had to deal with Microsoft licensing in over fifteen years, and unsurprisingly the topic doesn't seem to have gotten any easier since then.
You have to sail the high seas. Unless you are a business you cannot possibly get an LTSC license. Such a bummer that the quintessential Windows 10 experience cannot be bought by the average public.
Maybe I'll have to give Linux + Proton a shot, although I don't relish the additional complication regarding hardware selection...
Anyways, I'd recommend Linux gaming now to anyone if they have AMD hardware and value privacy. There are definitely still some quirks and typical Linux configuring but even for someone as impatient and intolerant to that stuff as me, it's been pretty good so far
