JkDefragGUI can do some basic cleaning to your profile or you may select to clean all the specified folder from every profile folder but you will have to have rights on all profile folders.

The Prefetch folder is used by Windows XP to speed the boot process. Windows XP records information about each program that launches at boot and uses that information to boot faster the next time. Because multiple files might have the same name, it appends a "hash" of the file's location. That's the odd string of numbers and letters between the filename and the .pf extension. This folder may accumulate useless junk, especially if you change your configuration a lot. There's no harm in emptying it. Windows will rebuild it as needed

Registry optimization calls an external program NTREGOPT. The optimization done by NTREGOPT is simply compacting the registry hives to the minimum size possible.

All these options except the registry optimization can be overwritten by an option from the options tab called "Use CCleaner instead" this options is only available when CCleaner.exe and CCleaner.ini are available in the programs folder. If CCleaner is installed on the computer it will be copied automaticly to the programs folder. The settings used by CCleaner are the ones in the CCleaner.ini, so the settings used can be different from the settings stored on your local computer.
