Windows update stops working after upgrade to Pro

I have a Samsung 7 Gamer laptop that comes with Windows 8 installed. I have an MSDN subscription and I wanted to install Windows 8 Pro. I have tried both adding the Pro code into the pre-installed Windows as well as a fresh clean install.

Windows Update is having problems. Updates are listing as being available but once the download starts it seems to just stop and go back to the list of updates. Or it sometimes says there are no updates available at all.

I have looked on the net and tried various steps there such as uninstalling my NVidia drivers, disabling all start-up services except Microsoft ones and running sfc /scannow via a command prompt.

I have looked into the log file and am seeing a few errors like these:

2013-04-21  15:26:29:464    1124    d74 DnldMgr   Download job bytes total = 1989293, bytes transferred = 1330139

Then further on:

2013-04-21  15:26:32:649    1124    d3c AU  WARNING: Failed to get Wu Exemption info from NLM, assuming not exempt, error = 0x80070490

It's almost like it starts to download then just decides to give up. I did manage to persuade some very small updates to install. But the others just fall over.

Any help appreciated!

Try the following, copy the text into a textfile (Notepad). SaveAs or change the file extension to "resetWSUS.bat" instead of ".txt". Execute the script by right clicking the bat file and selecting "..Run as Administrator". You must run the script as administrator.

This script will turn off a couple services, rename the folders and register a few dlls that Windows Update Services use.........
