Medion PC bought from Amazon 2 years ago. Windows 7 Home Premium. Was set up for auto update at 3am (the MS default) but has never been left on overnight, so never received any updates! Tried to update today. Fails with error 80070246. Tried several times - either fails within about a minute, or can take about 2 hours. Tried Control Panel | Troubleshooting Sytem & Security | fix problems with Windows Update - this ran to completion, did not report any corrections made, and afterwards the update fails in the same way. Tried Windows hotfix KB947821 "System Update Readiness Tool" - again, no reports of it doing anything, and no better afterwards. Stopped the update service and looked at: C:\Windows\SoftwareDistribution/DataStore C:\Windows\SoftwareDistribution/Download Some files in both these folders. Nothing readable. As generally recommended, deleted the contents of both these folders. Restarted the update service. Update now fails with same error in under a minute. It does write some files into C:\Windows\SoftwareDistribution/DataStore ... Googling hasn't suggested anything else ... Any ideas, please? TIA -- Graham J
With that error Microsoft suggests there may be corrupted parameter files and they recommend running SFC: http://support.microsoft.com/kb/929833
