Services run under their own desktop which is separate from the visual
desktop that the user sees.  As such, when you spawn a process from a
service, the process runs under the service's desktop, not the user's.  That
is why you can't see it.

You need to use CreateProcess() instead of ShellExecute().  The STARTUPINFO
structure that you pass to CreateProcess() contains an lpDesktop field that
you can fill in with the name of the correct desktop that the process should
run under, ie:

    STARTUPINFO si = {0};
    si.lpDesktop = "WinSta0\\Default";
    ...
    CreateProcess(..., &si, ...);
