The x64 ISA is backward compatible with the x86 ISA, meaning that x86 programs can run on x64 processors without modification. However, to take advantage of the increased address space and other x64 features, software must be recompiled or rewritten to use x64 instructions.

Let's say you're a developer looking to compile a 64-bit program on Windows using Cygwin. Here's a basic example:
If you are looking to utilize or "make" a feature functional from such a release, the standard procedure involves: Verification
