Windows 10 Update March 31 2017

This isn't even a workaround.
At least not for me...

I downloaded the nis_full.exe for my version of Windows Defender and ran it,
got zero, zip, zilch, nada.
This .exe file does nothing,
much like what the mpam-fe.exe did,
nothing.

Mine is still updating using Defender which will hopefully keep working until they fix Windows Update.

This is what I get from WD..

This is what my update history looks like,
using the WUMT...

Here are my results from running the WUMT...

FAIL!

Have you seen this thread? That registry edit mentioned there might help you. Good luck. :)

Thanks,
but maybe it's just me...
I don't feel that messing with the registry, is any way of getting Windows Defender definitions updated.

I fixed "my" issue by executing the following command in cmd as admin:

"%programfiles%\windows defender\mpcmdrun.exe" -signatureupdate -http

This is where I found the command and it's posting.
