I recently was sent a utility by a friend called 'TweakUAC', which he claimed could quiet down UAC such that it could still protect the system but stop prompting you for all the “Windows needs your permission to continue” boxes. Skeptical of this being some Trojan horse, I decided that I would figure out what it was doing in a VPC. Turns out it was writing a simple set of registry keys. So if you want to quiet down the UAC prompts you can set these registry settings. One is for the admin and one is for users:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
“ConsentPromptBehaviorAdmin”
and
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
“ConsentPromptBehaviorUser”
By default the value is set to 2. If you set it to 0 then you should be now operating with a quiet UAC. After the fact, I did some more googleing and found this article. Julie Smith basically calls out the same thing as my long protracted process came to the conclusion of. Next time maybe I should google a bit longer :$.
