Well I upgraded to Win7 and I don't like it at all, took two weeks to get it up and running 1/2 way, still has problems and I still end up with viruses have IYopi work on the computer all the time, more problems since I upgraded, and they say that windows 8 is worse.
If I had it to do over wouldn't have upgraded, went something is working good why not leave it alone. If you upgrade from XP you will need a lot of help. I couldn't get my external hard drive to work, I ended up playing with it myself and got it up and running. I keep all my embroidery designs on that, just in case the computer dies, will not loose the designs. Plus other important things like my Genealogy. To many year of things to loose everything.
