- runs any application[s] on a clean system (without system shell !!!)
- controls what applications can be started
- protects kids and computer

The program is generally designed for two purposes:

1. To run applications on a clean system. Running anything on a clean system (without system shell such as Explorer) has many benefits: more memory, bigger stability and often better performance. Gate Keeper allows to create a list of items (programs, multimedia clips, documents....). During system startup a dialog appears. -From then you can start Windows normally or run any set of items on a clean system.
2. To restrict access to the system. You can create program groups. Each group has its own password. During system startup the user is asked for password. If the user knows only a group's password, it will be only possible to run item(s) from the group on a clean system (so it is impossible to run anything else). Administrator's password gives access to all items or system, and system password gives access to the system.
