You are wrong
%1 passes long file names to 32 bit programs and Win 95 aware 16 bit programs. It passes shortfile names to 16 bit non win95 aware programs AND also to programs it can't find.
So in the command field in the registry change the path to cmd to something explorer can't find. Normally this occurs if the program's name is not enclosed in quotes (and there's spaces in the path).
Note Explorer builds a command line then gives it to CreateProcess to execute. Just because Explorer can't find a file doesn't mean CreateProcess can't. Try removing the path or something. MS refuse to say what Explorer's search alogarthm is (I suspect it just looks one place). CreatProcess' is well known and detailed below. I just add that it tries all ambigious paths as well..
This behaviour won't be chaged as some programs rely on this behaviour. MS did fix it but had to unfix it after application testing.
So in short there is no official way to force a shortname to be passed.
If the file name does not contain a directory path, the system searches for the executable file in the following sequence:
1.. The directory from which the application loaded.
2.. The current directory for the parent process.
3.. Windows 95/98/Me: The Windows system directory. Use the GetSystemDirectory function to get the path of this directory.
Windows NT/2000/XP: The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory. The name of this directory is System32.
4.. Windows NT/2000/XP: The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is System.
5.. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
6.. The directories that are listed in the PATH environment variable.
