Windows 10: Windows 10 Update March 31 2017

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. *Smile

Cumulative Update KB4016250 for Windows 10 v1703 Build 15063.11 - Page 2 - Insider - Windows 10 Forums

 

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. *Huh

 

I agree and would only try it if I was desperate and I had a fresh Macrium back-up to have as insurance. *Smile

 

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.

Definition Update for Windows Defender - KB2267602 Definition - Microsoft Community

 

Just another piece of the puzzle. Keep in mind, mine is on 15063.14.

Same ole ugly errors everywhere for Defender updates. Cannot use the direct link, DL'd file seems to do nothing when executed. Take this with a grain of salt, and I'm not suggesting this is a concrete solution, or 3rd party apps should be used, it just happened to work here. Using CCleaner, I checked off an option I never use, Windows Defender under Utilities. It cleans out Defender log files. After running CCleaner with this checked, WU processed normally, with no errors. No guarantee it won't get sick again, just that it worked this time. I've unchecked that entry for now to see what will happen going forward. Keep in mind, this is 15063.14, not 14393.969/970.










EDIT: 7:55am - just checked on my lappy running 14393.969, and it seems ok now! Has def 1.239.774.0, but shows as failed in Reliability History. Weird.......

 

Thanks for the tip f14tomcat...

I just used CCleaner to clear out the Windows Defender logs. Will post back to see if the next definition update installs without an error.

 

This is not really a fix, it's a workaround. You are just manually downloading the definitions and installing them. That's my guess unless you are saying that everything is now working properly after you ran what you posted.

 

Did not work for me. This is a Microsoft problem I think and I am going to use Avast temporarily until they get it fixed. Another MS fiasco!

 

The CCleaner tip did not work. Just got this:

There were problems installing some updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:

Definition Update for Windows Defender - KB2267602 (Definition 1.239.778.0) - Error 0x80070643

 

What I've done is create scheduled event that runs at user logon (delayed start for 15 minutes) spawning a batch file that contains "%programfiles%\windows defender\mpcmdrun.exe" -signatureupdate -http

Problem solved until MS fixes what they broke. I can run the bat file any time I want if I wish to update the definitions without waiting for the next time I start Windoze <tm>

 

No Joy for me - It said No updates needed ?

 

Hey, folks - it's a Microsoft problem. Not worth our time and effort to try to fix their problem. We just have to work around them by using 3rd party anti-virus or waiting until they decide to fix it, hoping we don't get infected in the meantime.
