Guide | How To Windows Defender - Definitions update (workaround)

[Kardo Kristal]

Here is a tutorial "How to update Windows Defender signatures" if you can't update it via inteface.
Finally I figured out workaround and it works for me very well.

1. Navigate to Windows Defender directory: C:\Program Files\Windows Defender
2. Now search for the file called: MpCmdRun.exe and create shortcut of it to somewhere (e.g. Desktop)
3. Right-click on this shortcut and choose Properties. now click on Shortcut tab
4. Under Shortcut tab set Target to:
"C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC
5. Click Apply and OK. After that launch shortcut, console window appears, wait until it disappears.

Windows Defender signatures should be now up-to-date (just check it via interface).

You can use this workaround manually or set up basic task under Task scheduler to automate it.
