The WOW64 subsystem creates a 32-bit environment on the 圆4-based versions of Windows. To view this document, visit the following Microsoft Web site: Running 32-bit Applications Program performance considerations For more information about the WOW64 subsystem, see the "Running 32-bit Applications" topic in the 64-Bit Windows section of the Microsoft Platform SDK documentation. The WOW64 subsystem does this by creating a 32-bit environment on the 圆4-based versions of Windows. The WOW64 subsystem enables 32-bit programs to run without modification on the 圆4-based versions of Windows. Additionally, the 圆4-based versions of Windows use the WOW64 subsystem to run 32-bit programs. The 圆4-based versions of Microsoft Windows are optimized to run native 64-bit programs. This article assumes that you understand the difference between 32-bit binaries and 64-bit binaries.
This article doesn't compare the 32-bit and 64-bit versions of Windows, or different 64-bit operating systems. This article describes some of the compatibility considerations for running 32-bit programs on the 64-bit versions of Windows. You can determine whether a program will have compatibility or performance issues by testing the program on one of the 64-bit versions of Windows. There may be considerations that affect a program's compatibility or performance.

Programs that depend on 16-bit binaries or 32-bit drivers can't run on the 64-bit versions of Windows unless the program manufacturer provides an update for the program. The 64-bit versions of Windows don't provide support for 16-bit binaries or 32-bit drivers. The 64-bit versions of Windows use the Microsoft Windows-32-on-Windows-64 (WOW64) subsystem to run 32-bit programs without modifications.
