An option I would like to see is if you set up ccleaner under one user, you can save the settings for all other users on the same computer so that if any new user is created, it will automatically clean everything out as perviously specified. A major drawback of ccleaner is that it's registry is edsigned for HKCU instead of all users - Can this be changed?
The main area for this is when several users log onto the same computer - in one case up to 200 students, I would like ccleaner to be automatically configured for everyone.
You can import the settings by exporting this key to "ccleaner_settings.reg":
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\CCleaner
Then import it onto the other user profiles by double clicking it, although you may have to temporarily enable Admin rights for non-Admin accounts to import the settings.
Edit:
To have it auto-import at every system startup just use something like this in the global startup folder e.g.; C:\Documents and Settings\All Users\Programs\Startup
C:\WINDOWS\regedit.exe /s "path to ccleaner_settings.reg"
Which could look like this:
C:\WINDOWS\regedit.exe /s "C:\Program Files\CCleaner\ccleaner_settings.reg"
