Windows 10: Windows 10 Update March 31 2017

Win 10 defender not updating.

I've found that it started when I clicked on the Creator notice on the Settings update page. I've done it twice after restoring from a backup. I'm still running on the Anniversary with all updates but clicked to be first on the Creator distribution.

 

I still have it on 2 pc's - how secure are they if definitions are not updating? Thanks MS!

 

Still received the error on the 4/3/2017 - 1.239.713.0 update.

 

I also have these errors.
I manually check for updates every day or so.
Error started for me on the 31st of March.
Was able to update by opening Win Defender,
but now that doesn't work as well.

 

Manual update works. For info go here.... http://www.thewindowsclub.com/update...ally-windows-8

 

Same here - not working on 2 pc's. Are we protected?

 

I downloaded mpam-fe.exe and ran it,
got nothing.

I ran the manual update using Power Shell,
here are my results.





What is the Windows Update applet,
I don't have it and never heard of it before?

 

Is anyone feeling we should install a 3rd party anti-virus in the interim?

 

I also got that error. Now I update from windows defender and then try windows update. Now I don't get error as defender is updated.

 

Just received a note in my Thread in the Microsoft Community. It's from Microsoft as follows. Hope we see their fix soon.:

Hi All,
Thank you for your patience regarding Windows Defender update error 0x80070643. We are aware of the issue and trying to roll out a mitigation as soon as possible. Meanwhile to get your machine back to a protected state, you can manually download and apply the latest Definition Update by following the instructions outline here: https://www.microsoft.com/security/p...tions/adl.aspx.”

 

This kind of workaround,
to get virus and spyware definitions updated,
seems ridiculous to me.
Does anyone agree?

 

Thanks for the new info. *Smile

 

I agree but at least there's a work around. *Smile

 

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.
