Windows 8 Pro x64 Windows Disk Cleanup with 'system files option selected' runs for 30+ minutes. Has anyone found a solution for this yet? After I stop Wuauserv and then delete all files in the SoftwareDistribution directory and then reboot. It still shows some 70mb of(Windows Update Clean Directory) files although there does not look to be any in the SoftwareDistribution directory any longer.

Any help is appreciated.
