Win 32 (WinAPI, Windows API) is a set of core application programming interfaces (APIs) available on all Microsoft Windows operating systems.  Though some programs use Native API, a majority utilize Win 32 to provide documentation and tools to aid developers in creating software associated with Windows technologies.

Functions of Win 32 Applications
Win 32 offers a host of services including:

• Base Services (file systems, processes, threads, devices, and error handling)
• Advanced Services (Windows registry, shutdown/restart system, start/stop/create a Windows service, and managing user accounts)
• Graphics Device Interface (output functionality for monitors, printers, and other devices)
• User Interface (creation and management of screen windows and basic controls), and various other functions
• In short, Win 32 helps you run/customize your PC.

Internet Explorer also utilizes Win 32, especially in imbedded web browser controls, URL monitor services, DirectX Transforms, XML support, and access to the Windows Address Book.  It also aids in program interaction and the function of wrapper libraries on your computer.

Your PC couldn’t run without Win 32 there to direct it, or at least provide the user with a means to do so.  All Win 32 applications are contained within your PCs DLL (dynamic-link library).  This library enables your PC to store, manage, and access all .dll, .oxc, or .drv files.

Maintaining Win 32 Files and Other Registry Files
Win 32 is beneficial to your PC because your PC pretty much runs off it.  Prevent any problems with Win 32 or your computer’s registry by downloading and utilizing a good registry cleaner.  This will help find and remove registry errors, prevent future registry errors from occurring, and keep your computer from dangerous crashes/freezes.
