Automatically Receive Critical Updates

If you need assistance implementing this step, please contact the ITU Support Center at (703) 993-8870.

• How?
  
  For Windows:
  
  1. Open Internet Explorer (Windows Update will not work if you use a different browser.)
  2. Go to http://windowsupdate.microsoft.com. Wait for the page to load.
  3. Then click Scan for updates. Wait for the scan to finish.
  4. Click on Critical Updates and Service Packs, if the option is highlighted. The updates in this category are important updates for Microsoft Windows and other Windows-related programs (Internet Explorer, Windows Media Player, Windows Messenger, Outlook Express, etc). We recommend that you install all critical updates. Click to install the updates. Follow the directions on the update page.
  5. You will need to accept the Microsoft License Agreement to continue.
  6. Wait for the updates to download and install. When they are done you will be prompted to restart your computer.
  7. It is a good idea to repeat the process until you are sure there aren't any more critical updates. Often, installing a major update like a Service Pack makes a whole new set of important updates available.
  
  For Mac:
  
  1. Open System Preferences from the Dock.
  2. Click the Software Update icon under “System”.
  3. Make sure "Check for updates" is selected from the Pull-down menu, choose "Daily."
  4. Check "Download important updates in the background."
  
  
• Why? Hackers can get into your computer through unpatched holes and take control of it, using it as a launch pad for world wide spam, denial of service attacks, and the distribution of illegal material, some of which could get you in trouble if it is found on your machine. They can also use your computer to bring down the university network, interfering with everyone's ability to do their job.
