It depends on the operating system really. The system processes of XP are different to system processes of Vista etc. Similarly, some VGA cards require EXEs and services running for them to perform. Most sound cards have some sort of minimized to tray program running etc. When you close any game, it should kill all its processes. If it is Vista, i think you can schedule the use of the system using parental control.

Just thinking out loud here (though if parental control works, as suggested by CodeCruiser, just stick to it)

1. Suppose you stick with the path you have now, create a simple startup-process that monitors the processes that are around at startup. It lists the PID and/or the name and simply kills everything else once it is triggered

2. Suppose you choose a different path and all you want to do is prevent your children from playing any longer and you don't want to be so rude as to kill any work they are in the midst of (writing an email or whatever). In that case, you can also just blank the screen with a top-most window.

3. Same as two but then you use a build in feature of Windows: the screensaver. But this time, you don't let the screensaver exit on the mouse move or input (maybe a special password can deactivate it, some password you set and not connected to current user).

all three approaches have some caveats and need some tweaking to be bullet proof, but it may give you some pointers on how else you could tackle this.

what I ended up doing was looping through all the process that were operating and inserting them into a database then every 60 seconds I loop through all the processes that are running and if they are not in the database killing them
Dear Abel
I would be curious as to how you blank the screen with a top most window or as I would prefer lock a particular program window on top of twhat they were doing

You can create a simple form, set its TopMost property to true, and set the ControlBox property to false. Then you could use a password on this form to close it.

Indeed, that's what I meant, thanks, CodeCruiser :)

I did what you said
>>set its TopMost property to true, and
>>set the ControlBox property to false.
but it still dissapears if you click its little rectangle on the task bar(if that is what you call it) to minimize it.
perhaps that's because id did not set a password But can you tell me how to do that?

You can trap the Form_Resized event and set the form to maximized again. This way, it would say full screen.

actualy I saw that I could set a minimize prprty to false and that prevented it from being minimized but How do I do the password thing?

Just hardcode a string in the form and add a textbox and button  on the form to match that string!

Exactly what property did you set to false to disable minimize?

Yeah that's what i originally recommended. You may want to use the resize event to avoid the form being minimized through ways such as Show Desktop.
