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.
