My old MS Windows XP.
Today I received a lot of prompts to reactivate my Windows XP, Media Center Edition, Version 2002, Service Pack 3. At first I was afraid it might be a hoax but then I recalled that MS said there would come a time when they would no longer suppport XP. I didn't relaize it was 10 years old. I have Vista on my laptop and never learned to like it. Then I heard criticisms about Windows 7 and chose XP to be the OS on my netbook. There was an offer to let me upgrade to 7 and I really don't know what to do. I guess if I turn on my netbook I will receive the same warning. As usual--any suggestions will be much appreciated. Thanks.
PS--Guess I should tell you I don't play games or do any social network stuff so getting all the newest for these uses doesn't matter to me.
