*** Based on FR comments at the time XP was crap, so I skipped it. ***
Not that it matters much anymore, but Windows XP was a decent, if insecure, operating system. If you kept it up to date with the latest Service Packs and regular updates in between, you had a pretty good system. It ran well on almost every computer out there.
Vista stunk because Microsoft loaded it down so much overhead that it couldn’t reliably run on the bargain laptops and desktops that Dell (and others) were pumping out like hot cakes. Windows 7 was considered by most to be pretty good. 8 was another Vista. So basically Microsoft puts out 1 passable O/S followed by 1 or 2 crappy ones. Your rolling the dice with Microsoft if you are an early adopter of their OS products.
I did have XP on my now long dead laptop. It was good. Vista is the system I skipped due to FR comments. I'm running windows 7. I tried 10 and hated it, so went back.
