Programmatically in rust or in general? Because there are many tools to find metadata on binaries on windows. Even though, you could still spawn a process and read the output. Depending on what you are going to look for, there are different tools you may need, for example if you want to check whether a binary is a .NET app, you could use dumpbin if I recall, and some other tools for other metadata. It all depends on what you want to do.
