I had a similar problem, but the error code were two diferents, one was 80245003 and the other I don't remember, but both of them I fixed doing this

Disable the Windows Update Service (Settings > Control Panel > Administrative Tools > Services). Just stop the service.
Navigate to: C:/Windows/ (or wherever you Windows system is)
Find the folder named: “SoftwareDistribution”
Rename that folder to something like “SoftwareDistribution.old”
Create a new folder called “SoftwareDistribution”
Go back to your Services panel and start the Windows Update service
Rerun Windows Update

thanks for the replies guys, but no dice. I still get the same error message after deleting the folder in safe mode, rebooting, and trying to update again.

okay, something weird happened when I tried to register qmgr.dll. an error message came up saying "the module qmgr.dll was loaded but the entry point dllregisterserver was not found. make sure qmgr.dll is a valid DLL or OCX file and try again." I registered qmgrprxy.dll just fine.

No it did not update. okay, I will wait patiently for a reply. thank you

well this is really weird. I've followed all the steps exactly and none of them did the trick. I used windiz and that sad that there were no updates needed for my computer, but Windows update said I had three updates. I may just have to reinstall the OS. Now that I think of it, the exact same thing that happened before. I'm completely flustered and you probably are too. I tried reinstalling the video drivers with no luck and I followed step eight exactly. when I ran the Windows update agent said it did not have to do anything. I appreciate all the help you have given me. If you happened to think of anything else just let me know. Thanks again, Jason
