How to update your computer

3. At the bottom left select windows updates then select Check for updates.
(Please Note: Just because Windows says "you're up to date" does not mean you are up to date.

Some updates may require a system restart to complete the installation.
This restart is not scheduled, so you can perform it at your convenience.
