Other DLLs and binaries are included for Itanium and ARMv8 64-bit architectures to provide emulation to x86 or for 32-bit entry points if the architecture has a native 32-bit operating mode.ĭespite its outwardly similar appearance on all versions of 64-bit Windows, WoW64's implementation varies depending on the target instruction set architecture. This is used in x86-64 implementations of Windows only.

Wow64cpu.dll, which takes care of switching the processor from 32-bit to 64-bit mode.

Wow64win.dll, which provides the appropriate entry-points for 32-bit applications (win32k thunks).

Wow64.dll, the core interface to the Windows NT kernel that translates (thunks) between 32-bit and 64-bit calls, including pointer and call stack manipulations.

WOW64 is implemented using several DLLs, some of which include: It aims to create a 32-bit environment that provides the interfaces required to run unmodified 32-bit Windows applications on a 64-bit system. The WoW64 subsystem comprises a lightweight compatibility layer that has similar interfaces on all 64-bit versions of Windows.

WoW64 aims to take care of many of the differences between 32-bit Windows and 64-bit Windows, particularly involving structural changes to Windows itself. It is included in all 64-bit versions of Windows-including Windows XP Professional 圆4 Edition, IA-64 and 圆4 versions of Windows Server 2003, as well as 圆4 versions of Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows Server 2012, Windows 8.1, Windows 10, Windows Server 2016, Windows Server 2019, and Windows 11, as well as ARM64 versions of Windows 10, Windows 11 and Windows Server 2022, except in Windows Server Server Core where it is an optional component, and Windows Nano Server where it is not included. In computing on Microsoft platforms, WoW64 ( Windows 32-bit on Windows 64-bit) is a subsystem of the Windows operating system capable of running 32-bit applications on 64-bit Windows. com /en-us /windows /desktop /WinProg64 /running-32-bit-applications
