About this article

One of the first things you need to do on your Windows PC is to check that it is running the most up to date version of the operating system. In this article, we are going to walk you through checking your operating system to ensure you have downloaded and installed all the latest patches and updates.

What is Windows Update?

Windows Update is a built-in feature of the Windows operating system that checks online as to whether or not you have the latest version of your operating system installed on your PC. This check is important as it can also contain security updates and patches to fix potential vulnerabilities in the operating system. It could also add the latest new features. As part of the update process, any new files will be automatically downloaded and installed on your PC. It's important to follow the update instructions as often your PC will reboot several times while applying these updates.

If you are running updates on a Windows laptop PC then it is often important to leave the laptop plugged into the mains supply so that it has an uninterrupted power supply during the updates.
