WOW64 is implemented using several DLLs, some of which include: [3] 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; Wow64win.dll, which provides the appropriate entry-points for 32-bit applications (win32k thunks)
In computing, Windows on Windows (commonly referred to as WOW) [1] [2] [3] is a discontinued compatibility layer of 32-bit versions of the Windows NT family of operating systems since 1993 with the release of Windows NT 3.1, which extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier.
x86-64 and IA-64 versions of Windows have two folders for application files: The Program Files folder serves as the default installation target for 64-bit programs, while the Program Files (x86) folder is the default installation target for 32-bit programs that need WoW64 emulation layer.
COMDLG32.DLL, the Common Dialog Box Library, implements a wide variety of Windows dialog boxes intended to perform what Microsoft deems 'common application tasks'. Starting with the release of Windows Vista, Microsoft considers the "Open" and "Save as" dialog boxes provided by this library as deprecated and replaced by the 'Common Item Dialog API'.
Folders which are presented to the user through an interface as an abstract concept, instead of an absolute path. This makes it possible for an application to locate where certain kinds of files can be found, regardless of what version or language of operating system is being used.

Due to problems with Windows applications being able to overwrite system files in Windows 95, Microsoft has since implemented a number of security measures to protect system files from malicious attacks, corruptions, or problems such as DLL Hell. System File Checker was first introduced on Windows 98 as a GUI utility. It offered scanning and ...
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs access API functionality via dynamic-link library (DLL) technology.
DLL hell is an umbrella term for the complications that arise when one works with dynamic-link libraries (DLLs) used with older Microsoft Windows operating systems, [1] particularly legacy 16-bit editions, which all run in a single memory space. DLL hell can appear in many different ways, wherein affected programs may fail to run correctly, if ...
