Yes, I also liked XP better than 7 and 7 better than 10... But 7, since it is not being updated anymore, has become less safe... Quickly as possible - understandable. I thinks your move from 7 to 10 was "inevitable" too. But now, when you have (quickly) got your new system running, you could try Linux. Sure, a lot of stuff has changed during 20 years. Linux history is not much longer than 20 years :smile: I think you could try some distros first in a VM (for example, in Virtualbox), without haste, step-by-step. A good starting point for choosing distros could be the advanced search on Distrowatch - "all rolling distros", and reading reviews. Unfortunately, I am not experienced in many different distros, because before Gentoo I had only Debian, it was a long ago. Since I found Gentoo, I tried other distros only for testing purposes, in VMs, mainly Debian/Ubuntu/Mint, a little - CentOS Stream and PCLinuxOS; liked, in general, all of them, except PCLinuxOS (a combination of non-systemd and rolling system seemed promising for me, but I didn't like how it all has been implemented and a general OS quality); CentOS is not for desktops, though, it's a server OS.
