Windows Defender is the security mechanism built into Windows 10 which is developed to protect both the computer and its components from various local and external threats. but beyond all this it offers certain functions to protect the data and even the kernel of the system if necessary. With Windows Defender we can have our computer protected against possible external threats that want to damage our system, so having it always updated is vital for optimal operation..
Windows Defender, like the operating system itself, receives updates periodically through Windows Update, but we may want to manually check for updates for Windows Update. In this case we have two options that TechnoWikis will explain in detail through this tutorial.
