Windows 10 Creators Update coming April 11th 2017

Fwiw, the Defender error is showing up for the regular non insider builds too. Updating from within Defender gives 1.239.785.0 as installed and up to date. WU still returns this error though.

Getting the same thing on two of my machines, Version 1607 (OS Build 14393.970).

This Defender update problem is a known issue, apparently. @jyim89 of the 'Microsoft Windows Defender Team' has registered on TenForums to say 'we know, we're working on it...'

For those experiencing Windows Defender update error 0x80070643 thank you for your patience. We are aware of the issue and trying to roll out a mitigation as soon as possible...

Cumulative Update KB4016250 for Windows 10 v1703 Build 15063.11

Thank you.

The Media Creation Tool from...
https://www.microsoft.com/en-gb/soft...load/windows10
... has just been updated to build 15063.



I'm downloading the combined 32/64 bit USB media as we speak...

Yay!

Update Assistant doesn't work for me...i went to the page from my update manager, and then to the link that microsoft provides...it downloads the file and when i click on the the file it just says: "thank you for downloading windows 10" and nothing happens...

I want to do an upgrade and not a clean install...seems like the assistant is not working properly at this point...

Just download the ISO file to your PC and mount it as a virtual DVD. Then you can double-click on the setup.exe to do the upgrade install.

Make sure to download a fresh copy of the Media Creation Tool to do that, it's only just been updated - the old one will continue to download the old .iso.
