Your operating system is the central software that runs your computer. Security vulnerabilities are sometimes discovered and the manufacturers often release updates or patches that secure these vulnerabilities. It is therefore important to keep your operating system up to date.
Microsoft Windows Automatic Update checks for security repair, compatibility updates and new drivers. It does this by running in the background whilst you are connected on the Internet, and where updates are available, downloads them onto your PC.
