I had Win3.1 and I reluctantly switched to Win98...and I reluctantly switched to Win XP. I now realize I waited until I got the 'good' systems. My wife's laptop has Win7 (she barely found one after they started pushing Win8), and it seems to be 'ok'.

I bought as a 2nd machine, 3 years ago, a DELL with XP installed, but a disc for 7 included.

I'm thinking...........
