I don't know why you refer to that page, but when you get to the
business-end of that page, the "what to do bit", you find:

*Minimum supported client* Windows XP [desktop apps | UWP apps]
*Minimum supported server* Windows Server 2003 [desktop apps | UWP apps]
*Target Platform* Windows
*Header* synchapi.h (include Windows.h)
*Library* Kernel32.lib
*DLL* Kernel32.dll

 Where you can see that Windows.h is clearly capitalized (while other
headers, clearly (and correctly) are not).

Windows file system does not care whether it is capitalized or not,  and

It does actually, ntfs is case-sensitive. For backward compatibility (I
presume), explorer, cmd.exe etc, add a case-insensitive layer on top of the
native file-system. Clang-cl warns about mis-matches in casing.
