Do you have a copy of unsupported software hidden in a sub folder anywhere on your local drives? Client of mine had an old copy of the Novell client installer (it was never installed on this machine) sitting in a folder named C:\Old_Computer\ . Last year's fall update kept aborting with an unclear error dialog. The install log only gave a vague suggestion that the issues was unsupported software and DID NOT reveal the full path to the offending file, just the title of the software. Windows desperately needs a shibboleet option, so power users can stop fighting it.
