In Vista Microsoft changed a few Rules in how programs can run and behave.
Those "rule changes" are a good thing.
If a program has problems with those rules, the problem isn't Vista's its the program's. (Complain to the program's creators)
In Vista each user has two modes of operations (Restricted & Elevated), to operate by default in resistriced (including Adminstrators).
When a program needs to do something the requires special permissions, then it seeks the user permission to do.
-When granted Vista temporarily raises the permission levels (Elevation) and right its done lowers them.
In XP it like switching from a Standard User (which you should use primarily) to an Administrator, do what you need to do, then switching back.
A program running on XP under a User who has administrator privileges could do whatever it wanted.
This is why users complain when their machine gets infected by malware and virus. It because they are running as Administrators
In Vista the Elevation prompt is to tell the User, that this program need special permission to do something.
Ask yourself the question what was doing that need elevation.
If you weren't doing anything, its possible that
could be malware.
Vista UAC ExplainedWell behaved software should only ask for elevation during Installation & Unistallation.
UAC What. How. Why. UAC In more detail.
When I find again, there an Interview with the creator of UAC.
