Where can I find a free program to run two copies of the same program?

Question

Software and Internet Services

Are there free programs for Windows that allow you to run 2 copies of the same program at the same time? Maybe there is some way to do it other than to download the prog? The only thing I found was "run as..." but that doesn't work.

For a more general case,
Windows Container
