Hi
Disable UAC
To disable the UAC, enter the Control Panel and type UAC in the search box.

The first result returned by the search will be User Accounts – Turn User Account Control (UAC) on or off.
Click on it and the UAC window will open. Deselect the option Use User Account Control (UAC) to help protect your computer and press the OK button.
Windows Vista will ask you to restart your computer. After the restart, UAC will be disabled
It is very important to turn this back on after making your changes.

 

thanks Mr. Gery, but i can't turn on or off my account because it protected by account administrator. i have 2 account active now in administrator mode, but i have not account in standard mode. my friend was doing something on my computer later. he was deleted something on main account setting. i confused now, i cann't do anything for my computer. please help me to stop "permission by account control" >>

please reply on my e-mail [email deleted by Admin: we only post responses here on the forum]

 

This is not you?

I would get ahold of your "friend" and find out what he did.

Is this a work computer?
