Windows Update

Windows Update is the online extension of Windows that helps you to keep your computer up-to-date. Use Windows Update to choose updates for your computer’s operating system, software, and hardware. New content is added to the site regularly, so you can always get the most recent updates and fixes to protect your computer and keep it running smoothly.
 

• How do I know if I need an update?
• Windows Update scans your computer and provides you with a tailored selection of updates that apply only to the items on your computer. During the scan, a list of categories appears under Welcome to Windows Update and the number of updates that are available in each category is noted in parentheses.

• 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.

• How does it all work?
• Follow a simple, three-step process to get the updates you need to keep your computer up-to-date:
  • When you enter Windows Update, click Scan for updates.
  • As you browse through the available updates in each category, click Add to select the update of your choice and add it to the collection of updates you want to install. You can also read a full description of each item by clicking the Read more link.
  • When you have selected all the updates you want, click Review and install updates, and then click Install Now.
• Note Some updates may require that you restart your computer. Save your work and close any open programs before beginning the installation process.

• Have questions about an update?
• Each update is accompanied by a brief description and a Read more link. Click Read more at any time to view information that is specific to each update. Included in this information are system requirements and, if applicable, instructions on how to use and how to uninstall the update.

• To see the list of updates you have installed from Windows Update, click View installation history.
• *SPECIAL NOTE: Under the Update Driver section, it is probably best not to update your drivers from here. If you need to update your drivers, visit the manufacturers website for more information.
