Update Your PC Automatically
To help keep your PC more secure and reliable, it's a good idea to install new updates as soon as they're available. The easiest way to install updates is to use the Windows Update service and make sure automatic updating is turned on.
In Windows Vista, you can set Windows Update to automatically install both Important and Recommended updates. Optional updates are not downloaded or installed automatically. If you choose not to turn on automatic updating, please make sure that you check for updates regularly.
