How to turn off UAC (user account control) in Windows Vista
Windows Vista introduced a new security feature called User Account Control (UAC).
Generally, it's a good idea to leave UAC turned on, but sometimes you'll need to turn it off (to install some software, re-register PowerPoint, or for other software maintenance tasks).
If so, here's how:
- Click the Start button, point to Settings, then click Control Panel.
- Click Classic View then double-click User Accounts.
- Click Turn User Account Control on or off.
- If you see a User Account Control dialog box, click Continue.
- Remove the check mark next to Use User Account Control to protect your computer.
- Click OK.
When you're done with your maintenance tasks, repeat the same steps, put a check mark next to Use User Account Control to protect your computer and you're done.
