Guidelines for Securely Configuring your Computers

Please observe the following guidelines for maintaining your computing devices:

1. Keep your computer with the latest patches
     Windows and all software require regular updates. Updates can improve security and reliability of your computing devices.

      2. To manually check and install the latest updates, type “Windows Update” in the search box (next to start menu) to activate the application.  If it shows Updates Available, click “Install Now”. 
      3. Restart your computing device upon the completion of the installation of Windows update.
