Updating Windows 8
Windows 8 carries on the tradition of periodically offering security fixes, new hardware drivers, and other updates for the operating system and Microsoft software. Some of these are critical fixes that should be applied as soon as possible, while others are simply recommended or optional updates that you can install if you wish. When you first personalize Windows 8, you are asked how you want the operating system to handle updates. You can install them automatically, download them but choose whether to install them, check for updates but choose whether to download and install them, or never check for updates.
