If you are a capable Windows OS user, you will probably want to turn off User Account Control (UAC) in Windows Vista. Most users will find the constant interruptions everytime you want to install or open a program very annoying. To turn of UAC, go to Start, click on Run, type in msconfig and press Enter. The System Configuration window opens. Click on the Tools tab. Scroll down till you find "Disable UAC" . Click on that line. Press the Launch button. A CMD window will open. When the command is done, you can close the window. Close msconfig. You need to reboot the computer for changes to apply.
