Computer shutdown

I am sometimes in a hurry at work and I need to run CCleaner before I leave my desk. I would like a feature attached to CCleaner that would turn off my computer when it finishes its job. Maybe this feature is already there and I just haven't found it yet. Any ideas?

schedule a logoff task on CCleaner using task scheduler to run it at logoff and it will run everytime you shut your computer down but make sure to add the /AUTO command

...or download the batch file I made called CCleaner Auto Shutdown from my signature below.
