Windows Vista sucky error message

Just got a new box which had Vista Home Premium on it -- I'm trying to upgrade to Vista Ultimate which I already had. (Would have preferred XP Pro but it wasn't available on the machine.)

In any case, after going through the long process, the error message that shows up is something like:

"One or more services couldn't be installed. Upgrade failed. Restart computer and start installation again."

Message to Microsoft -- warning messages like that are bush league, they suck and appear to be designed to piss people off (perhaps you should see who is advising you to use such stupid error messages). At the very least, there should be an option to see more data on the problem. Vista OBVIOUSLY knows which services it couldn't install -- perhaps a list of them might help.

Why the hell a company like Microsoft can't think about providing useful data instead of apparently just trying to protect us poor users from some underlying complexity is beyond me.

And, by the way, I like MS products -- I am not an MS basher like some people I know.

But, this kind of stupid message is absurd!
