Windows update fails - Windows 7

I cannot seem to install the latest updates for my copy of Windows 7 Professional. I keep getting these same error codes each time:

Code 66A - Unknown error
Code 8007006E - Unknown error
Code C0000020 - Unknown error

I've run virus scans with 2 different virus software apps and there aren't any infections. Does anyone have a solution to this, preferably one that doesn't require a lot of twiddling with the registry and such...

Is there a MS Fixit for this?

Thank you!

You need to run system readiness tool first and then restart the computer.

If u have win7 64 bit then run this

If u have win7 bit then run this

After restarting install updates. If still having problems then upload checksur.log.

Thanks, but I had already tried the update readiness tool and the update troubleshooter without success. I found the solution to 2 of the problems on my own:

SOLVED! Code 66A - Unknown error - I went to programs and features and ran a repair on Microsoft .NET Framework 4 Client Profile

SOLVED!Code C0000020 - Unknown error - I set the folder "WMI" located at C:\Windows\System32\LogFiles\WMI and all child items within to full control for my user account in the advanced security permissions. Also, had to set the folder "winevt" located at C:\Windows\System32\winevt and all child items within to full control for my user account AND full control for the "eventlog" object in the advanced security permissions.

Still trying to resolve the Code 8007006E issue without having to reinstall my office installation. Any more suggestions? Thank for the comments so far.

Security Update for Microsoft Office 2007 (KB951550)
Security Update for the 2007 Microsoft Office System (KB951944)
Update for Microsoft Office 2007 System (KB2508958)
Update for Microsoft Office Outlook 2007 Junk Email Filter (KB2586924)
Update for the 2007 Microsoft Office System (KB967642)

These are the ones i have tried to install. If i install them individually i get the same error with each one.

Known issue with security software....put the computer in clean boot mode and then install the updates.

Clean boot process

Start-type - msconfig- click on startup tab- click disable all...then click services tab- put a check on hide all microsoft services ...and then click disable all....click ok and then restart the computer in normal mode.

Now install the updates manually...Reboot ...come out of clean boot .

upload the checksur.log

Try uninstalling your security software...reboot and then try to install the updates.

Several ideas here
http://www.eggheadcafe.com/microsoft/Windows-Update/35142907/error-code-8007006e--windows-7.aspx
Have you tried installing 2007 Microsoft Office Suite Service Pack 2 separately from the others?  I wonder if there is some conflict between what updates are needed before and after installing the SP2.

Log points to .net framework error

SQMAPI.DLL Not Loaded      0x000000C1


check this article

Use the clean up tool to remove .net and then do windows updates to install all .net framework

If nothing works then try repair install

Boot to desktop...insert the windows 7 disc...launch setup...click upgrade option....this will repair your windows install... complete the repair install.

You will not loose any data or programs during the repair install process

if sp1 is installed then you need to integrate sp1 and then perform repair install.

After repair try installing updates.

Thanks for all the comments but i was able to resolve the Code 8007006E issue. I had ended up having to manually uninstall the office installation using the fixit located here:
http://support.microsoft.com/KB/928218
...and then reinstall Office 2007.
