With the Automatic Updates feature, Windows can keep your computer up to date automatically with the latest updates and enhancements. You no longer have to search for critical updates and information; Windows delivers them directly to your computer. Windows recognizes when you are online and uses your Internet connection to search for downloads from the Windows Update Web site. An icon appears in the notification area each time new updates are available.

You can specify how and when you want Windows to update your computer. For example, you can set up Windows to automatically download and install updates on a schedule that you specify. Or you can have Windows notify you whenever it finds updates available for your computer; it will then download the updates in the background. This permits you to continue working uninterrupted. After the download is complete, an icon appears in the notification area with a message that the updates are ready to be installed. When you click the icon or message, you can install the new updates in a few simple steps. If you do not install a specific update that has been downloaded, Windows deletes its files from your computer. If you change your mind later, you can download it again by restoring declined updates.
