What identifiers do programs have?

Question

Windows

How does windows distinguish between different programs and in general does this happen?
Let's say I compiled 2 programs using the same code and windows distinguishes between them, although the compiled code is the same, which should produce the same control weights.
So if you try to look at what the game is doing with the help of monitoring programs, the game also notices it, they do not determine it by name ... So how?
The question is not only related to Windows, just would like to know all the possible ways.
I know that it is possible to encode receiving, checksums \ weights usually use 3-5 different ways at a time.
Windows issues a security id.
What else is there?

Answer 1

Apparently, we are talking about the GUID of the program.
