ok, i know this behaviour.
The reason for deactivation of the UAC are the nerving question as admin if you want to do some things as admin. If you disable this for admin you don't have this question.
In a German Vista you can do this on the following way:
Start --> Ausführen --> msconfig --> Enter --> Tools
There you find "Benutzerkontoschutz deaktivieren"
You can control this in the Registry:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
More about this you can read
here. If you find there an Reg_Dword ConsentPromptBehaviorAdmin with value 1 or 2 you need your patch. Otherwise not.
