Is there a programme to hide active programme..?

in order not let any one exit the prog i wanna hide..

Yes there is a very easy way, takes about 10 seconds to set up but I am not going to tell 'cause how do I know you will use it for good rather than evil?

This sounds illicit.

Yes and no. In older operating systems, such as Windows 95/98/ME, hiding the running applications was easy. This was because these operating systems rated pretty low on the security scale.

With Windows NT/Server/XP/Vista, it's a bit more difficult.

You can't hide running processes in these later operating systems. The user can always bring up task manager and view them. It's possible to have a process running as a user other than the currently-logged-in user, and if the current user does not have administrative privileges, it will not be visible.

You also have the ability to run the software as a service, which does not show up as an individual process (even though the system will have a process running that contains your software). Even then, the user can stop your service via Control Panel -> Administrative Tools -> Services, assuming he/she has the appropriate privileges.

Put simply, if the user is without administrator privileges, then yes, you can prevent him/her from stopping your software. If the user is an administrator, he/she can stop your software.

This is, of course, the way things should be. The human should always be in control.
