When you use `process' or `system', the immediate subprocess is a shell
(i.e., cmd.exe). So you're killing the shell that started Notepad, but
not Notepad itself.

If you use `(process* "c:/windows/notepad.exe")', then the 'kill
control should work as you expect.

Meanwhile, MzScheme exits when its stdin is closed, so that's why
MzScheme exits when you close the ports.
