Yes I did stop using computers during that time. While I had my Amiga in school only nerds had PCs, so I didn't get one, even though I was programming on my Amiga with AMIGABasic and so on. I guess it was mostly because I started doing normal teenager stuff once I was 16 like motorbikes, cars, playing music, going to the clubs, etc. so there was no time and no desire to use a computer. Only once everyone seemed to have internet at home I started feeling left out a bit. for some months I started usincgcomputers in Internet Cafes and then decided to get a used PC.
On my duel booted system I still have windows. But I haven't had to use it in a couple weeks and at this point might just delete it and go fully into Linux only. Just a few windows only apps that are making me unsure. Might try windows vm.
Honestly if I played any games that had anti cheat I would run a windows vm in QEMU/KVM. Go the GrapheneOS route and sandbox the spyware (cough Google and Microsoft cough)
I have a Windows install that I haven't booted up in 2 years. I didn't really use it anyway. I just had one thing to finish there, but I am lazy.
I only used it for a few weeks after getting that laptop while waiting for Linux kernel 5.8 which would finally support that hardware as nothing older booted up.
