How to Keep your Operating System (OS) Updated

As the discovery of existing vulnerabilities in Operating Systems (OS) becomes a common occurrence, we would like to remind you to keep your Operating Systems up to date. Doing so will help to protect you against potentially malicious attacks, and maintain system stability.

To install the latest updates for your particular OS, please follow the instructions for your Windows or Mac operating system below. NOTE: If you have previously enabled automatic updates, you may already have the latest round of updates (instructions to enable automatic updates is included below).


Windows 10 users:

  • Click the Start menu and then Settings. In the Settings window, choose Update & security.

  • Click Windows Update on the left hand side of the Update & security window, then click Check for updates (if updates are already available, click Download.)

  • If updates are available, Windows 10 will download and install them.

  • Once the updates are installed you should reboot the PC.

  • After reboot, repeat these steps until there are no more updates to install.

Windows 7 / 8 users:

  • Open Control Panel from the start menu, and choose Windows Update

  • Click Check for updates for your computer to begin searching for any updates you have not yet installed.

  • If/when updates are available for installation, click the Install Updates button (the installation may begin automatically depending on the version of Windows you are using, and the way Windows has been configured).

  • Once the updates are installed you may be prompted to reboot the PC. At this stage, save any work and close all applications to reboot.

  • After reboot, repeat these steps until there are no more updates to install.

  • NOTE: Optional updates are not critical and do not have to be installed unless you specify otherwise.


  • If you wish for Windows updates to be installed automatically in the future, see the information under ‘How do I keep my PC up to date’ here:

  • IMPORTANT NOTE:  When you enable automatic updates, you are allowing updates to be installed in the background, potentially while you are working. This can cause temporary performance issues while the install is occurring. After updates are installed, your PC may automatically reboot, resulting in the potential loss of any work that you have open on your desktop (though you should receive a message about this before it happens). For this reason, always save and close any important work before leaving your PC for any length of time.


Installing the latest updates on your Apple Mac is a simple process. Open the Apple Store app on your Mac, and click ‘Updates’ in the toolbar. If updates are available, click the Update button to download and install them.

If you are using an older version of OS X (10.7 - 10.12), you can upgrade directly to the latest version (10.3 High Sierra), by doing the following:

  1. Click on the Apple icon in the upper left corner of your screen.

  2. Click on App Store....

  3. Click on Featured.

  4. Click on macOS High Sierra in the Mac App Store.

  5. Click on Download under the Sierra icon.

  6. Wait for macOS High Sierra to finish downloading.

  7. Click Install to begin the installation process.

Please note that major OS updates can take some time to install. We highly recommend that you backup your data before performing any major OS updates.
