Did the sfc fix the problem? If not then according the log there was corruption during a windows update. After some research those files that were corrupted during the win update cannot be deleted because they belong to windows update "trusted installer" account". You'd have to take control. My only suggestion then would be try a repair/install with the installation disk. Otherwise this is far as I can help as I'm not familiar enough with correcting corrupted update files.
Do you know what windows updated recently? Because that's what looks like what might be causing all the problems.
