Warning: Linux Evangelizing in 3..2..1..
For anyone who is/may/eventually/has to buy a new PC and have Windows on it (like if Windows 11 obsoletes your current system and will not work with it), I would like to suggest that you don’t donate/throw away your old system immediately. As soon as you’re “done with your old PC” *and it’s trash to you*, try installing Ubuntu (it’s free) on it and give it a chance. I suggest Ubuntu only because it has a “simple/normal” installer and should just work. I’m sure some other Linux users would disagree with me
yes, you’re going to feel like ubuntu sucks because it doesn’t look and act exactly like Windows, but just try it out. Browse the web, check your email, install whatever and try to do your “normal stuff”. Just test the waters of not using Windows. Likely you’ll find that there is something you just have to have that’s only Windows compatible, and that’s good because then you can decide if that’s reason enough you need Windows in some future PC purchase.
If nothing else, it might give you reason to keep your old PC and get more life out of it vs throwing it in the trash.
if you’re not “a computer person” or don’t have the time or care to mess with it, sure don’t give it a try. It’s not for everyone but it may open your eyes to exactly what you need/use that’s Windows only and it might save you some money in the future should it be useful to you.
note: switching away from Windows is not always a walk on the park because “everyone uses Windows”.

you will no longer be part of the 98+%? of people (who all use Windows) and are likely going to have issues with something (like finding out steam will install, but not all steam games you bought support Linux) hence only attempting to try it out on a junk PC you’re no longer going to use for *anything*. In my opinion Windows is more “user friendly” and more “user resilient” for certain things (like finding how to fix PC problems on the internet) so it’s a good choice to keep Windows for someone already using Windows who doesn’t want to mess around with or learn about computers. Linux is for people who are willing to learn something new for (insert reason).
