Here is how I was able to work around the problem.
Using command prompt
1. proxycfg -d (to clear proxy cache)
2. net stop wuauserv (to stop Automatic updates service)
Using Windows Explorer
3. Delete all files and folders in
C:\WINDOWS\SoftwareDistribution (your windows folder may vary)
Again using command prompt
4. net start wuauserv (to start Automatic updates service)
Try now going back to Windows Update web page.
It worked for me. YMMV

"Hi,
I had the same problem with windows updates and tried all the remedies
posted on umpteen replies and none worked.
I then found while scouring the net this piece of information of which -
BINGO - it worked! (not sure if its in the forum anywhere but here it is
anyway)"
Re-register the WU components:
1. Quit all programs that are running.
2. Click Start, and then click Run.
3. Type "regsvr32 wuapi.dll" (without the quotation marks), and then click
OK.
4. When you receive the "DllRegisterServer in urlmon.dll succeeded" message,
click OK.
If this does not resolve the problem, repeat inputting the following
commands and click OK after each command.
regsvr32 wuaueng.dll
regsvr32 wuaueng.dll
regsvr32 wuauserv.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wuweb.dll
regsvr32 iuengine.dll
"A couple of these regsvr32's did not register but I ignored them and as I
stated it still corrected the problem.
I sincerely hope it helps anyone who is going nuts trying to sort the
problem out!"
