• How do I know if I need an update?

• Critical Updates are important!
  Any update that is critical to the operation of your computer is considered a "Critical Update," and is automatically selected for installation during the scan for available updates. These updates are provided to help resolve known issues, and to protect your computer from known security vulnerabilities. Whether a critical update applies to your operating system, software programs, or hardware, it is listed in the "Critical Updates" category.

Windows Update uses ActiveX controls to check what software is installed on your computer in order to provide you with a correct list of updates and other software you may want to download.
