You can schedule your own Windows Defender definition updates.

1. Create the following bat file:
C:\Program Files\Windows Defender\WDSignatureUpdate.bat

@echo off
"C:\Program Files\Windows Defender\MpCmdRun.exe" SignatureUpdate

2. Create the following scheduled task:
"C:\Program Files\Windows Defender\WDSignatureUpdate.bat.lnk"

Schedule the task to run whenever you want.

I created the task...However, in the "Run: box in Scheduled Tasks, the
WDSignatureUpdate task is called "C:\Program Files\Windows
Defender\WDSignatureUpdate.bat", not
"C:\Program Files\Windows Defender\WDSignatureUpdate.bat.lnk".

If I change it to "C:\Program Files\Windows
Defender\WDSignatureUpdate.bat.lnk", (as in your post) it will not run.

I ran both with full admin rights. Whay am I doing wrong?

Cheers-

Jason, the .lnk extension is a shortcut to the bat file. I chose to
reference a shortcut instead of the actual bat file so that I could assign
shortcut properties to cause the task to run minimized.

Create a shortcut to the WDSignatureUpdate.bat file and modify the
shortcut's properties to run minimized.

"C:\Program Files\Windows Defender\WDSignatureUpdate.bat.lnk" is the
reference to the shortcut, not the actual bat file.
