I have a laptop still with Windows 10. I got it from my late sister about 4 years ago, booted it up, went and installed Ubuntu (18.04 at the time), and never touched Windows again.
I later read somewhere that W10 was forcibly upgrading itself to W11, so I’m afraid to even boot into it. Should probably take some time to copy everything important over and finally nuke it.
For reference, I’ve been using Linux since around 2012.
Basically Loopy in Simon Tatham’s Puzzles, available on Linux, Windows, and Android (F-Droid), when I don’t want to be stressed.
Otherwise I just play some retro/old school games like Final Fantasy (started IV a few days ago), (Free)Doom, AssaultCube or Cave Story when on my laptop.
