Windows 7 Service Pack 1, error 0x80070643
Hi, I have been trying to install the Windows 7 SP1, unsuccessfully, for most of a week now. The update does not appear in my Windows Update program, so I used the online version on Microsoft.com. The update installs correctly, but after restarting and beginning the "configuring windows" process, it only reaches about 50% before it states that there has been a fatal error and reverts the changes. It goes into a mini-loop where it configures and then reverts several times, before finally restarting with all changes reverted. I always get error code 80070643. I followed all the directions for this error on Microsoft.com, including running the System Update Readiness tool (no errors) and the sfc scan (also no errors), disabling the firewall and all anti-virus programs, and uninstalling/reinstalling the .NET framework. I also tried downloading SP1 to my desktop and running it that way to bypass any problems related to my internet. I posted on Microsoft answers and received no replies, so any help I get here will be greatly appreciated. I've attached my log collection. Thanks again!
