In the latest Build 9879 disk cleaner takes about 2 minutes before it comes up. I have no idea why. Hoping someone here might have the answer.

You must delete the Win old folder and the Windows -bt folder, it will then run normally. You can probably do this by running the disk cleaner as system. I changed the permissions and did it that way.

Added. I think Ccleaner will also do this in the latest version.

Thanks Kemical. I wasn't sure if it was just mine or not. Had no problems with previous builds.

Had same problem. Tried to turn off wormhole defender and it stalled out on doing that just like it stalled out on ccleaner.
Rebooted then turned off defender. CCleaner ran ok then. Turned defender back on.
