Fresh installed Win10 Pro; run update, all updates went through except Definition Update for Windows Defender - KB2267602 (Definition 1.231.456.0) -Error 0x80070643.

Have tried several times since this morning without success.

What is happening?

What antivirus do you have installed ?

If you don't have any other AV, open Defender and try the update from there.

No AV installed.

Tried update from Defender with this error:

"Virus spyware definition : Connection failed.

The virus and spyware definition didn't update on 27/10/2016, 2:43 PM because of an Internet or network connectivity problem."

My network/ Internet connection has no problem; I can access the Internet from IE /ffox no issues.

Googled and tried everything available but still couldn't get it to install the definition update!

Re-install (clean install - wiped the HDD) run Windows update, all updates installed except the KB2267602 failed to install.

Any other suggestions or, this is the way Win10 updates?!

Any other suggestions or, this is the way Win10 updates?! For some reason, and there can be one of several, there's some sort of setting not right. it happens sometimes. That error is often caused by some other third party software that hasn't disabled defender like its meant to ( that's why I asked if any were installed). Sometimes they get stuck for one reason or another in the softwaredistubition folder as well.

I do hundreds of updates and rarely have any problems. If there are problems being in front of the computer its usually easy to sort out what the problems are.

Have a read of this thread, (completely) https://social.technet.microsoft.com/Forums/windows (https://social.technet.microsoft.com/Forums/windows/en-US/3aa4fbb8-9a33-4172-95c4-173f4741aa7e/definition-update-for-windows-defender-kb2267602-definition-122324830-error-0x80070643?forum=win10itprosetup). Theres several options, as well as a link to manually download, and how to run the trouble shooter for updates.

I had one problem update couple of days ago, it was a new HP laptop the person had Office 2003 ( yes 13 years old) and 1 update wouldn't install for office, manually downloaded the KB, installed it - perfect. :)

Hows this for ironic :) Just doing a setup for a brand New ASUS Laptop, on the first run of the updates the exact same error on the same KB.( this laptop had crap-a-fee live installed)

Working on its fix now.

Update to my Update :D

Problem fixed.

Ran the update trouble shooter - bottom of list from https://support.microsoft.com/en-nz/kb/2970908 Problem was some sort of screw up with .net Framework

Now upgrading to the latest version of W10.

Hmmmm Sounds like its corrupted someplace.

I found the following on another site. People had same error and same KB

Open a CMD as admin, either type or copy / paste the following, press enter after pasting/entering. ( including the "")


"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -RemoveDefinitions -All

Then:


"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -SignatureUpdate

Sometimes when trying to find a fault/ cause its a case of run something, suck it and see what happens. Its when it turns to bad, then ya gotta know how to undo things.

Had people think I'm joking when I say that at their houses :)

Back to work, just got another Laptop to fix along with the other 3 PC's on the benches - Who said I'm finishing at my normal 5 pm today -- HA!
