Should I be using win 10 or win 7?

8.1

Name 5 simple tasks it fails to adequately perform.

LAN file transfers, burning disc images, searching for files, automating actions, recognising file systems.

I give up already, there are some retards who ignore 8.1 and switch to spywareX from windows 7

Every Windows version since XP has a universal backdoor.

I'll accept recognising file systems, but you'll need to elaborate on the other 4.

I have yet to find a way that works for those four things.

Those 4 things are all possible on Windows.

How?

install gentoo
