How do I start an application with a certain windows size an in a certain position? I would like to start it via command line, or by launching the app with a shortcut. In my case it's File Explorer. The solution has to work either for Windows 7 and Windows 10 but it does not have to be the same solution.
Unless absolutely necessary I want to do it without 3rd Party software. The question that is supposed to be a duplicate only received answers for 3rd Party software solutions; the other question specifically asks for a software solution as well, my question does not.
