Since June 18th 2012 Windows Update has been trying to install a new Windows Update Agent and has failed repeatedly.
I have rund the Fixit's without any help. I have run the fixes described at http://support.microsoft.com/kb/2509997 which are:
Method 1: restart your computer, and then try to install the updates again
Method 2: Run the System Update Readiness tool (CheckSur.exe)
Method 3: Run the System File Checker tool (SFC.exe)
Method 4: Reset the content of the Catroot2 folder
Method 5: Remove any incorrect Registry values
Method 6: Register the Windows Update files
Method 7: Make sure that your antivirus application does not scan certain files
Method 8: Rename the SoftwareDistribution folder
Method 9: Clear the BITS queue of any current jobs
Method 10: Download and manually install the 958056 update
Method 11: Rename Pending.xml
Method 12: Run Chkdsk on the Windows partition
I also ran the items on page http://support.microsoft.com/kb/957310 with no success. I see that someone else has the problem and built a custom solution, but didn't really share it, see http://social.technet.microsoft.com/Forums/en-US/winserverwsus/thread/226d7698-c6d4-4783-8534-b955d4a441aa and I have tried to conntact Microsoft Support but can't get through.
I am running Windows 7 professonal 64 bit version 6.1.7601 service pack 1 build 7601 on a Dell xps L502X with an Intel i7 2670QM and 8 GB of ram. This is the error it gives me and of course I have followed these links to no avail.

The Windows Update Agent enables your computer to search for and install updates from an update service. The agent can automatically update itself as needed to communicate with the update service when Windows searches for new updates.
