Greetings, On Windows 7 Enterprise, 32-bit, with SP1 installed, the following 11 updates repeatedly fail with error code 0x80070020: kb2644615 kb2639417 kb2618451 kb2633952 kb2584146 kb2619339 kb2618444 kb2620712 kb2631813 kb2656356 kb2633171 Windows update always says these updates were successful and to restart now. However, when Windows restarts and reaches 35% completion, the system reverts the changes. I have tried multiple FIXITs with no success. Any thoughts would be appreciated.

I had already run multiple FIXITs, including that one. THey did not work. DocComputers verified since 1972

I am down to only KB2633171 now. It is the only one that will not install. DocComputers verified since 1972

Update: Problem resolved. This was a PC for a friend that I was helping with over the phone. A full scan of MSE did not reveal any issues with viruses. On the chance that it was malware blocking this update, I had the user create a Windows Defender Offline boot CD and run a full scan overnight. It found one issue, which it corrected. Then, booting the OS installed KB2633171 successfully. DocComputers verified since 1972
