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 that is included on all 64-bit versions of Windows—including Windows XP Professional x64 Edition, IA-64 and x64 versions of Windows Server 2003, as well as 64-bit versions of Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows Server 2012, Windows 8.1 and Windows 10. In Windows Server 2008 R2 Server Core, it is an optional component. 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. ==Translation libraries== The WoW64 subsystem comprises a lightweight compatibility layer that has similar interfaces on all 64-bit versions of Windows. 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. Technically, WoW64 is implemented using three dynamic-link libraries (DLLs): # Wow64.dll, the core interface to the Windows NT kernel that translates between 32-bit and 64-bit calls, including pointer and call stack manipulations# Wow64win.dll, which provides the appropriate entry-points for 32-bit applications# Wow64cpu.dll, which takes care of switching the processor from 32-bit to 64-bit mode抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WoW64」の詳細全文を読む スポンサード リンク
