The UAC in Windows Vista can be really annoying. It doesn't really do much since since it justs asks for confirmation and after the 100th time it asks, most people stop paying attention to what it is saying. The good news is that it can be disabled. To do so, follow these steps:

1 - Click start and type in CMD

2 - Copy and paste the following into the command bar: C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

3 - Restart your computer (it is Windows after all)

4 - Now instead of the annoying UAC prompts, you will get annoying prompts about the UAC being disabled. Thankfully, these can be disabled too by following these instructions:

4a - When you get one of the prompts, click the bubble

4b - On the side, it will say: Change the way Security Center alerts me. Click on that.

4c - Click: Don't notify me and don't display the icon

You have now turned off your UAC notifications.
