A program is a set of instructions for the person in the room to carry out. Looking at it in this fashion, it is easy to see that the process itself doesn't do any work, but the thread does. A thread lives in a process, and executes the instructions of the program.
The diagram below which is in the Windows Internals book shows how the components interact. The thread is what Windows schedules for execution within a process.

The diagram isn't wrong, it just isn't applicable to versions of Windows prior to Windows 8. Harry: I'd believe that the author wasn't really interested in showing how the Win32 subsystem relates to everything else, but I'm just not believing IE built directly on the native interface. Rewriting it in. NET, I'd believe, but not the way the diagram is now. Oh, I see what you mean.
A hello world program is a frequently used programming example, usually designed to show the easiest possible application on a system that can actually do something i. Over the years, various changes and additions were made to the Windows Operating System, and the Windows API changed and grew to reflect this. However, in general, the interface remained fairly consistent, and an old Windows 1. A large emphasis has been put by Microsoft on maintaining software backwards compatibility.
To achieve this, Microsoft sometime even went as far as supporting software that was using the API in a undocumented or even programmatically illegal way. Which is why I get particularly furious when people accuse Microsoft of maliciously breaking applications during OS upgrades.
If any application failed to run on Windows 95, I took it as a personal failure. While Win32 was originally introduced with Windows NT 3. To ease the transition, in Windows 95, both for external developers and for Microsoft itself, a complex scheme of API thunks was used that could allow 32 bit code to call into 16 bit code and in limited cases vice-versa.
So-called flat thunks allowed 32 bit code to call into 16 bit libraries, and the scheme was used extensively inside Windows 95 to avoid porting the whole OS to Win32 itself in one chunk. In Windows NT, the OS was pure bit except the parts for compatibility with bit applications and the only thunk available was generic thunks which only thunks from Win16 to Win32 and worked in Windows 95 too. The Platform SDK shipped with a compiler that could produce the code necessary for these thunks.
The name of the API however was kept consistent between different Windows version, and name changes were kept limited to major architectural and platform changes for Windows. Although Microsoft's implementation of the Windows API is copyrighted, it is generally accepted that other vendors can emulate Windows by providing an identical API, without breaching copyright.
