This document outlines how to perform a Windows Update on your Microsoft Windows PC. Microsoft's Windows Update is a relatively easy way for securing you computer.

  • Updating Windows from the website

      *The website will check to see if you have the latest version of the Windows Update program on your computer.

    • Choose Express to check for High-priority updates. Windows Update will check for High-priority updates for your PC and display them for your review. Select the updates you want, and then click Install Updates
