The HINSTANCE returned by ShellExecute() is not a valid HINSTANCE, as stated
in Microsoft's own documentation:

    Return Value
        Returns a value greater than 32 if successful, or an error value
that is less than or equal to 32 otherwise. The following table lists the
error values. The return value is cast as an HINSTANCE for backward
compatibility with 16-bit Windows applications. It is not a true HINSTANCE,
however. The only thing that can be done with the returned HINSTANCE is to
cast it to an int and compare it with the value 32 or one of the error codes
below.

Use CreateProcess() instead.  It returns a process ID, which you can then
use with EnumWindows() and GetWindowThreadProcessId() to find any windows
that have a matching process ID.
