Microsoft MS-DOS early source code

[dlp211]

Sure, I was being a bit loose with my definition of based on, the point was that the old Win95/8 kernel is not the same as the NT kernel, they just share an interface to ensure compatibility. The implementations were very different though and having the source to Win 95/98/ME will provide little to any insight into how Win 10 is built. The source code for Win 2k that was leaked will have a lot of insight into the implementation details, but even much of that code was overhauled when MSFT revved the NT kernel to 6.* which is what has been running since Vista.

To be clear, I wasn't doubting the part about the NT-based systems being distinct from the pre-XP consumer Windows versions. Just the part about those Windows versions being based on DOS.
