KIOSK Admin Tool takes advantage of KDE's KIOSK restrictions framework. It is centered around profiles. A profile is a collection of default settings and restrictions that can be applied to either individual users or groups of users.
Typical usage of KIOSK Admin Tool is to create a new profile, then to set up the profile with the desired default settings and restrictions, and finally to activate the profile by assigning the profile to one or more users or to a group of users.
1) Open the terminal and fire command : # kiosktool to open the main KIOSK admin window
2) Now you can create a new profile, after creation click on "Set up profile" to do the actual restriction on the desktop
