As for Windows, I bluntly can say that 8.1 is by FAR the best version they ever made, yes you need OpenShell to fix the user interface but when it comes to performance, reliability and compatibility it absolutele beats the snot out of every other version even 7.
7 is very good but lacks a few things like SSD support out of the box and several other things also, I can install and update 8.1 still today, 7 needs a bit of work or you have to use WSUS to get the updates.
10 is where the crap starts, it's all in all pretty meh..
11 is a vibe coded mess and unreliable.
Honourable mention XP with service pack version pack 4, yes, that's 4 it's not official but it will instantly completely update XP SP3 to the latest software, it will for example add support for exFat.
Windows XP Service Pack 4 Unofficial is a cumulative update rollup for Windows XP (x86) English as well as security enhancements not addressed by Microsoft....

If you have a 4GB machine with a single core or slow dual core then this is very usable.
Win2K if you have a Pentium II with 256MB RAM or up then this one will work smoothly and reliable.
Linux, yes you need to get into it but there's a distro for everyone out there.
