no, i installed it - used it for a few days to see if i liked it, it downloaded all the updates - including one which was supposed to make your activating vista experience easier, well it didn't, brand new ultimate bought 3 days before i tried to activate it and it says the key is in use, i rang MS, they told me to ring the 0800 number to activate it - if it wouldn't they would give me a new ultimate code.
They did say that the WPA/WGA update may be the issue, so when i got my new pc i activated the git first, no problems that time 🙂
