Vista’s User Access Protection (UAP) Depending how you look at it Vista’s User Access Protection (UAP) is on it its best or worst features.
In short every time you want to do anything that could possibly threaten the PC’s security or change Windows settings a message box pops up onto the screen demanding to know if you really mean it, or it asks you for a password or change your account status.
For most users it is unnecessarily, annoying and a touch nannyish. If you are the only one using your PC, and you reckon you know what you are doing one of the first things you will probably want to do is switch it off.
To do that go to Run on the Start menu or press Windows Key + R and type ‘msconfig’ (without the quotes) and select the Tools Tab.
Scroll down the list, highlight ‘Disable UAP’ and click the Launch button. A DOS type command window opens, click the exit icon to get rid of it, reboot the PC and you won’t see the pesky warnings again
I left mine on....sort of "Vista for Dummies" or "Mother may I".....for me!
