Our company would like to install CCLEANER in all our PCs. So at boot-time, the AUTOEXEC.BAT will run CCLEANER / AUTO to clear out all the temp files etc (too many people complain say not enough disk space).

a) However, we don't want to empty the trash - anyone know the switch to not clear out the trash? Can't find in the Piriform Forums.

b) We also want to clean the registry, but the documentation say cannot clean registry unattended or silently. If so, anyone got recommendation for Registry Cleaner with command-line parameters?
