This worked good for me on a Fresh install...

During Fresh/Custom install, select "Install Important Updates Only".
In Control Panel, under Power Plan Options, select "Never Off" for monitor and computer.
In Windows Update, change setting to "Never Check for Updates".
From a thumb drive on a different computer, download from Microsoft the fix called KB3135445.
Run this fix until it installs itself. You may need to try it several times and reboot til it installs.
Reboot, and then try Windows Update again.

Within 10 minutes, Update had found 153 updates. I clicked OK, and it immediately started to
download and install all 153 updates.
It takes about 3 hours to download and install the updates, and everything appears to be back to normal.


I found this fix after trying several re-installs, and Fix-it tools and Diagnostic tools. Pretty much wasted 4 days,
clicked on too many things, and tried to install too many fixes.
