I have a question that is kind of bothering me. I love this forum and like to play around with this stuff on VM's and a test computer it's a lot of fun but I have two computers with legitimate Home Premium installed which is more than enough for my real computing needs.The question is I entered an ultimate OEM key that matches my computer into anytime upgrade just to see what it would do. To my astonishment about 10 minutes later I had an ultimate edition lol. Now I'm kind of worried since this is my main box and I really don't want to lose it. Should I be concerned about this? It was so easy and now I'm leery of updates and stuff which was never a concern with this machine. I don't really use any of the features except xp mode and frankly virtualbox is much better. Is there any way to detect an illegitimate anytime upgrade?
