Hello, I've got the following question:

Is it possible te disable everything in windows except the program it's running?

I need to program an application on a touchscreen (fullscreen), where people can fill in a survey.
The only thing they should use is this program. (for protection of the survey anwsers and other secret stuff :p )
And the program should be closed when entering the right password.

So how can I disable everything else but the program I'm running?

Thanks
