Windows 7: Cannot open windows update GUI on VM desktops

I have two production VM desktop images that I maintain on a regular basis, both of which are having the same problem. I can get both of them to run windows update from the command line, but I do not have the icon in my start menu or windows update listed in my control panel. I believe it is related to the VMware optimization script (attached - Commands.txt) I ran against them when I first built them (around a year ago), but I have backed out all of the changes from the script that seemed to have to do with windows update. When I run windows update from the command line I get the notification in the system tray that there are updates to install, but I cannot right click or double click on it to bring up the GUI either. I have to restart the machine to let it do the install automatically. Here is what I have tried so far:

I set the following keys:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate]
"DisableWindowsUpdateAccess"=-
"DisableWindowsUpdateAccessMode"=-
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoWindowsUpdate"=-

I set the local computer policy for automatic updates to not configured

I used Microsoft FixIt to update Windows Update components

I tried Microsoft kb906602 - troubleshoot common installation issues in Windows Update

I updated to the latest version of Windows Update Agent

I backed out the following changes from the VMware script:
Powershell Set-Service 'wuauserv' -startuptype "disabled"
reg ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" /v NoAutoUpdate /t REG_DWORD /d 0x1 /f

I made sure the BitLocker Drive Encryption service was running

At this point I'm not sure what else to look at. The only error I see in the Windows Update log (also attached) is the following: 2012-08-22 14:54:46:096 436 d8 CltUI FATAL: Failed to open Microsoft.WindowsUpdate page "<home>", hr=80004005

Windows update is running though so I don't think the problem of opening the GUI would be found there, but I am not sure. Any help would be greatly appreciated. Thanks!
