Why should I update my operating system?
Updates contain important security measures, such as patches and upgrades, which help keep your computer safe. Install new updates as soon as they are released. If you are unsure if your system is up-to-date, it's important that you check immediately.
While it is always good to be mindful of your operating system's state, you can save yourself significant maintenance work by configuring your system to install updates automatically.
Guides for checking for, installing, and configuring automatic updates can be found by the manufacturer of your version of operating system.
