If you are not into gaming... try Ubuntu. It's Linux based, easier to use than windows, is open source so costs nothing (including software), and bug free.. ... I am a home user, not at all a computer whizz, and since installing it over a year ago on my first machine have not touched window.
Until I stopped using Windows I thought all the problems were just normal... they aren't. Windows is a really bad operating system unless you have some compelling reason to use it.
Just google Ubuntu... you won't look back if you make the swap. Try it on an old worn out machine that won't run Windows anymore first... You will be amazed that Microsoft has got away with it for so long!!!
