Hi!

Only one instance of NTWDM could be in the memory. If you kill it, you will kill all DOS or Windows 3.* programs currently running.

There are special API functions for DOS programs that are located in the separate DLL. I do not know details, but you can try to search from this side. Try also to send this to some other forums that are more related to API functions and low-level programming for Windows (For example, C++ forums).

I can also post a sample of correct killing of windows application, but I did not tried it with DOS program (just to compare with your code), if you want.

>But, there is one problem. I can find the window handle by the window name. I can find the process handle related to the DOS window name. That process handle points me to CMD.EXE, and if I try to kill it, nothing happens to actual DOS window, despite the return code from TerminateProcess API function is 1. In order to kill the real DOS process I have to kill the related ntvdm.exe.
