The context of this question, is here.

I actually know the answer to my question is yes - like I say in my context, this program can do it (somehow).

So the really question is, how can I do it. What code do I put in a simple batch file? (or do I have to compile a tiny c++ exe? and run that exe in the batch file?)

Might this code be a solution? (.....EnumDesktopWindows?)

To clarify, I know that there's e.g. NirSoft OpenedFilesView which shows allll the technically-opened files in Windows, but it's just the 'visible' user-opened ones that I'm after (whatever you can see in Task Manager's Applications tab).

Thanks.
