Option to Clean Later

There seem to be only two choices... either clean a browser or not have it watched anymore. When I try to dismiss the clean I get asked if I don't want to monitor the browser anymore. I know I am not saying this well but I think you know what I mean.

I would like there to be a choice when I cleaned a browser ten minutes ago and have to reopen it and close it - I would like option to choose to clean later -

You could achieve this using the built-in Windows Task Scheduler by setting a set time when you know you're unlikely to be using your computer, and the command-line parameters (see the docs) to automatically run CCleaner using the /AUTO switch

CCleaner.exe /AUTO
