What is Windows Update?

Microsoft has a utility called "Windows Update" to help keep the Windows Operating System current and up to date.

If your computer runs a current version of the Windows Operating System (Vista, 7, or 8) you should download and install all "Critical Updates" from Microsoft.  Critical updates repair flaws in the operating system that will protect your computer from the malicious acts of others on the Internet.  To check if you have the current Windows Updates, open Internet Explorer, click on Tools, and click on Windows Update.
