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.

This process can be automated if it is the case, for this we open a notepad and enter the following commands:
"% ProgramFiles% \ Windows Defender \ MpCmdRun.exe" -removedefinitions -dynamicsignatures "% ProgramFiles% \ Windows Defender \ MpCmdRun.exe" -SignatureUpdate
We go to "File - Save as" and in the "Type" field we select "All files", we enter the desired name with the extension .bat. We click on Save to complete the process.
After this we will go to the path where we have saved it, right click on the .bat file and select "Run as administrator":
