The Verge is reporting:
Microsoft is releasing the source code for its original Windows File Manager from nearly 28 years ago. While it's a relic from the past, you can still compile the source code Microsoft has released and run the app on Windows 10 today.
The source code is available on GitHub, and is maintained by Microsoft veteran Craig Wittenberg under the MIT license. Wittenberg copied the File Manager code from Windows NT 4 back in 2007, and has been maintaining it before open sourcing it recently. It's a testament to the backward compatibility of Windows itself, especially that this was originally included in Windows more than 20 years ago.
A port of Microsoft's File Manger made its first appearance in OS/2 1.1 and then became the primary file manager in Windows 3.0.

Whenever they make something good, it is almost a given that a new version will be forced down that ruins it, so they may fix it again.
Case in point, whenever I have to use the file managers in the later versions of Windows, I'm always fighting to get the default options to remain set the way I want them.
It would still be nice if they released the source for the Windows 95/98/2000 file manager. Throw in the Visual Studio 6 IDE and I might start to believe that they are getting serious about open source, but it would have meant much more 5 or 10 years ago.
To me it no longer matters.
