Windows 10: Windows Defender Signature Updates not working automatically

hello,i have an issue with Defender signature updates. We have a Win10 Enterprise LTSC Client 21H2 which is connected to an internal WSUS-Server above GPO.The problem is, that the signature updates doesnt work automatically. Manually starting the defender updates work.Also the windows updates are working automatically, but the Defender signature updates doesnt updates.The workaround with an script and scheduled tasks also work, but i want to know why the automatic defender updates dont work?!This ist the output from: MpCmdRun.exe -removedefinitions -all Service Version: 4.18.23110.3 Engine V

SEtting up automatic updates for windows defender on windows 8

I have found this on the internet en have set up a task for automatic definitions update for Windows Defender but a window pops up when this starts to run.
Is there a way to set this without any window popping up so that it just runs in the background?

Now I'm using
"C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC

I'm currrently using it as described here:

my windows defender is not updating

Hi Rob,

The error message 0x80240022 is caused by an outdated Windows Defender signature.

Here's a step by step instruction on how to update the signature for Windows Defender:

• On the "Search" bar, type in Settings
• Click on "Update & Security".
• On the left pane, find Windows Defender. Click on it.

• Select the Update tab.
• Select the Update definitions button.

If the Update definitions finds a new update signature, it will automatically download and install it.

NOTE: Make sure that the download file is 50MB or larger. This is to ensure that you are downloading the complete update file.

Let us know if you were able to complete the update.
