One of the biggest criticisms Windows Vista receives is for the User Account Control (UAC) prompts. While this is a security feature by design which is often blown way out of proportion (as you can probably tell, I don’t think they are a big annoyance at all), instead of completely disabling it, try TweakUAC.

This free program offers 3 modes:

• Off - no explanation needed.
• On - the opposite of ‘Off’.
• Quiet - prompts to do administrative tasks (i.e. open Computer Management, etc.) will not prompt you for confirmation, however UAC is still in full effect for user accounts. This is probably the option most should select.

You can read a full description of each mode on TweakUAC’s download page. Like everything, greater security comes with the price of lost convenience (think airports).
