Does Windows support running a program from memory?

Question

I found out that you can run the program from memory in Windows. But is this functionality considered hacking (which one day no longer works), or does Windows support this functionality?

This is one thread that talks about this topic: CreateProcess from memory buffer

Answer 1

Windows does not support starting processes from memory, only from a file. Running processes from memory is a hack that relies on undocumented implementation details that can be changed. In other words, MS could perfectly change the design of the system in a future version of the OS, so the existing launch from the memory code stops working.
