User Access Control is that annoying thing that keeps on popping up tirelessly to ask you if it is OK to install a particular program when you try to install one. It is one of the biggest irritants in Vista, but I must warn you that disabling it will render your system less secure.
1. Open the Control Panel, type in user account in the search box, and press [Enter].
2. You’ll see the link for Turn User Access Control (UAC) on or off. Click it.
3. Uncheck the box, reboot your computer, and you will no longer be bothered by UAC.
