 Other Windows API Implementations  edit
Microsoft is no longer the only provider of the platforms implementing the Windows API: just by far the most dominant. There's also 
Wine (providing support for Windows apps on platforms like 
Linux, 
FreeBSD and 
[BeOS
]) and 
ReactOS (providing an alternative Windows compatible operating system).

getWindowsAPIVendor is a small but handy proc for detecting which win32 code base your app is really running on: 
Wine, 
ReactOS or Microsoft Windows. This can be used for tuning your app or informing the user of support/non-support.
