I'm also trying to schedule ccleaner to run automatically at a given time. I followed all examples in the "How to enable the CCleaner AUTO parameter" post but can't get the ccleaner shortcut to run. When I click on it, it does nothing at all. If I remove the /AUTO from the "Target" description in Properties, it'll run fine...but I'd like it to automatically run minimized and then close with no prompting on my part. Is there another way to do this? Or could there be a reason the /AUTO won't work for me? (My OS is WinXP.)
