Microsoft tells Windows 10 users to just trade in their PC for a newer one, because how hard can it be?

This is a most excellent place for technology news and articles.
Just use Ubuntu. (Surely I'll get hate for this.)
It's based on Debian, a major branch off the tree. It just fucking works. Millions of tutorials, groups, etc. to find troubleshooting info. Probably won't have to do anything to get a machine running that does everything you're doing now.
Get the swing of that and go from there, if you want to try other branches.
This realization helped me quite a bit: Windows does all sorts of arcane voodoo with the registry and DLLs and such. Weirdness Linux appeals to many because all the configuration is contained in simple text files. Got a program that reads and writes plain old text? Aight. You can configure Linux. In a way, it's so simple it's hard to get your head around coming from Windows.
tl;dr: Just download and install Ubuntu. Go from there with your nicely working machine.
Yes, I hate it.
Use Mint - it works better than Ubuntu, Canonical has made enough 'mistakes' to get on the blacklist.
