Does Windows supports running a program from memory?

Question

I have found out that you can run a program from memory in Windows. But is this functionality considered to be a hack (that could one day not work anymore), or does Windows supports this functionality?

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

Answer 1

Windows does not support running processes from memory, only from file. Running processes from memory is a hack that relies on undocumented implementation details which are subject to change. In other words, MS could perfectly well change the system design in a future OS release such that existing run from memory code stopped working.
