Desktop Cleanup Wizard serves to maintain a clean desktop that does not retain unused shortcuts. Desktop Cleanup Wizard checks for unused shortcuts (not in use for the last 60 days) and deletes them without affecting the installed programs. This function is set to 60 days. When Desktop Cleanup Wizard is carried out, all the unused shortcuts are stored in the Unused Shortcuts folder on the desktop. User can restore the shortcuts moved to this folder to the desktop again.
