This way it doesn't get any further into your system and you clear up some clutter, with a machine you can allocate to something else. > another Buster PC I do bits of programming on. Perhaps upgrade this to your main box, which you also do your programming on? > Windows PC I play poker on and some games. The only games I play are Chess and Go, but I believe Linux also has poker, although I don't know how well that integrates with online game venues. Install Steam, and you have it all! The last time I used a Windows box was when XP came out, and that was one of their better ones. But, I actually bought a second-hand Windows 10 box recently (HP EliteDesk G1), and all I use it for is a driver box for better scanners and printers Linux doesn't cater to as yet. When the market picks up in that regard, I'll probably turn it into a home theatre box running Kodi.

Depending on your desktop, it can be quite easy. KDE run a gui set-up that you barely have to think about, but config files for back-up ninja and a couple of others are, literally, trivial to figure out. Not that I can talk. I didn't become the world's foremost authority on reinstalls by backing up. It's for chickens! But keeping a separate \home partition is good policy. Cheers!
