Yeah XP was good...I got 7 with new computer so no choice, always worked fine tho.I was most happy with windows XP pro. It was the best OS I ever used. I tried the upgrade to 7 when support for xp ended. It was a complete nightmare for me. It was touted as the best and most stable of any iteration of windows, but it was horrible to me. Constant blue screens and lock ups. So when the free upgrade to 10 came along it was like "what do I have to lose at this point" and it does at least work, though I find it to be NOT very user friendly (for this user). My previous system died and when I bought the present one, 10 was all I could get. I also dislike the loss of privacy and automatic tracking and everything that goes along with that. I'm sure by the time we get to windows 12 it will be automatically wiping our butts for us (if we'll let it) as well as telling us what we think...
