Earlier today I had a system that would not install Windows 7 64bit Service Pack 1 via the update process. Here’s how I got around it:
- Open Control Panel and turn off auto updates.
- Browse to C:/Windows/SoftwareDistribution/Download
- Delete all contents in the Download folder but do not remove the folder.
- Next browse to C:/Windows/SoftwareDistribution/DataStore
- Delete all contents but again do not delete the folder itself.
- Open the Logs folder and delete the contents. Do not delete the Logs folder itself
- Open a browser and go to http://go.microsoft.com/?linkid=9665683
- Download and run this fix
Note this has two modes Default and Aggressive. Try Default first.
- Restart the computer.
- Turn Windows Auto Updating back on
- Run Windows Update to download and install the latest updates
If this process doesn’t work then try running the fix in Aggressive mode
Note: for items 3, 5 & 6 you may find some files are locked and you are unable to delete them. If so then make sure Windows Auto Update is off and reboot the system. You should now be able to remove them.
Note too that even after this I had problems deleting one file in the DataStore but Windows did allow me to rename (strange). After I did this I was able to delete it.
Hope this helps
