Windows on Windows
In computing, Windows on Windows - commonly referred to as 16-bit WOW, WOWEXEC or simply by its acronym WOW - is a compatibility layer of 32-bit versions of the Microsoft Windows NT family of operating systems that extends the NTVDM to provide limited support for running legacy Win16 applications written for Windows 3.x. With 64-bit-based systems "WOW" generally refers to support for running 32-bit applications on 64-bit versions of Windows, known as WOW64.
== Background ==
Many 16-bit Windows (Win16) legacy applications can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow application developers time to remediate their applications during the industry transition from Windows 3.1x to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before ''all'' the applications used by a customer had been taken care of. However 32-bit versions of Windows are in decline, with support already dropped for server platforms with the release of Windows Server 2008 R2.
The Windows 9x series of operating systems, reflecting their roots in DOS, functioned as hybrid 16/32-bit systems in the sense that the underlying operating system was not truly 32-bit, and therefore could run Win16 applications natively without requiring any special emulation; Windows NT based operating systems differ significantly from Windows 9x in their architecture, and therefore require a more complex solution. Two separate strategies are used in order to let 16-bit applications run unmodifed on 32-bit NT-based versions of Windows (with some runtime limitations). They are called thunking and shimming.
