Why Won't My Microsoft Updates Install?by Matt Skaggs
Microsoft OS updates are crucial to security and compatibility, but installing them can sometimes be frustrating. The solution is usually fairly easy to implement, if you know where to look.
Sometimes Microsoft provides an error code, such as "0x80070005" or "0x80070422." A Google search or a search in Microsoft's Support site will usually define the error message. Eric Brodish, a program manager for Microsoft, has provided a list of these errors on Microsoft MVP Sandi Hardmeier's website (see Resources).
If you cannot even download updates, you may be offline. The Control Panel -- found by clicking the Start button -- contains information and procedures for connecting to the Internet. In Windows 7 and Vista, the Network and Sharing Center in the Control Panel provides Internet connection information and fixes. In Windows XP, the Network Setup Wizard in the Control Panel provides step-by-step instructions for connecting to the Internet.
Automatic updates are available only for Microsoft XP. Originally Windows XP updated through Internet Explorer; later Microsoft created a Control Panel updater, which is necessary to continue receiving updates. Installation of automatic updates can be done through Microsoft's website. (See Resources.)
There are many causes of failed update installs. It may be necessary to use a troubleshooter to solve the problem. A troubleshooter narrows the problem's cause through questions and prompts. (See Resources for online troubleshooters.)
