WoW64 is implemented through several key dynamic-link libraries (DLLs) found in the system:
: Because x86-64 processors support 32-bit code natively, there is often no noticeable performance loss compared to running on a native 32-bit OS.
: On x86-64 systems, the processor can switch between 32-bit and 64-bit modes natively, which makes the translation process computationally inexpensive.
