WoW64 is implemented through several key dynamic-link libraries (DLLs) found in the system:
: On x86-64 systems, the processor can switch between 32-bit and 64-bit modes natively, which makes the translation process computationally inexpensive. Wow64 Microsoft
: 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. Wow64 Microsoft
: Provides entry points for 32-bit applications, specifically for GUI and windowing functions (win32k thunks). Wow64 Microsoft
