Oh I know it can be installed, but after the headache I got re-installing 10 once before and then trying to get 11 running on...anything, really, i just decided "you know what? What will be will be at this point. I'm not gonna need it for much anyways." when i finally got 11 to accept and install into a random external drive that i never really used (it didn't like the one i had inside my PC reserved specifically for it. Somehow...).
(Note: this was a while back, so installation could be a helluva lot better now and i have upgraded a bit since then but, shrug. Already got Windows ready to go on a drive, and only have it because I might need it moreso than me actually wanting to have it, so meh)
Two things made me leave. Both having to do with Windows.
Microsoft themselves.
My Windows install was just...bad. I'm not sure how else to describe a Windows that frequently crashed and just gave up and Blue Screen. Sure, both probably happen to any normal Windows install (well, the 1st thing. If you get the second, yeah that's a problem)--but not at the frequency it happened with mine, I'm sure. Besides that, it was slow for no reason (AFAIA, anyways) and doing anything took a while. Yeah, I eventually reinstalled it after some hassle, and after that it was just slow, but then i made the fatal mistake of trying Windows 11 and was like "if this is what I'm eventually ganna have do deal with...no thanks." Tbf, Microsoft was promting it, so i assumed it was an upgrade to Windows 10, not a wannabe chromebook with some baffling "lets fix what isn't broken and works great as is" choices.
Well, thinking about it, there was a third reason i ususally neglect to mention:
As for what I am, IDK. I'm a happy Linux user, but i also get some people are perfectly happy Windows users (or aren't, but are locked into the ecosystem regardless) and hey, as long as we agree that both OS's have their quirks, you let me keep my penguins, and I'll let ya keep your...erm, Windows (does Windows have a mascot? I doubt it, but you never know)
