because you nearly always need to run as admin. In xp you run all your programs as admin. I think microsoft wants vista to be better protected in using most programs without administrative rights.
An elevated process may take control over a not elevated process, and got more rights.
Some programs even run faster when elevated, while some won't run at all if not elevated.
A good example is ET. PB may require ET to be run as admin, this means a minimizer and ventrilo push to talk won't work unless those programs are also run as administrator.
The basic idea is that you limit the amount of damage a potentially dagerous program may cause if it's not elevated.
And just elevating the processes you really trust.
well the rule is DON'T. if you dont have to to get it too work. like ET. Its a safety feature to prevent viruses and such to get installed on you computer.
But I hate it as well so blame mikroschrot.
