On my machine platform.win32_ver() and sys.getwindowsversion() are returning different Windows build numbers. I have confirmed this with Python 3.7.6, 3.8.5, and 3.9.2 (all 64-bit) on Windows 10.

platform.win32_ver() returns:

    ('10', '10.0.18362', 'SP0', '')

sys.getwindowsversion() returns:

    major=10, minor=0, build=18363, platform=2, service_pack=''

The sys.getwindowsversion() value is correct.

The Windows About panel reports Windows 10 Enterprise, version 1909, build 18363.1440. My kernel32.dll version is 10.0.18362.1350.

I'm also able to reproduce the problem you just described. It's actually not the fault of platform.win32_ver. Just type in sys.getwindowsversion().platform_version and you'll achieve a similar result. Behind the scenes platform.win32_ver is actually deriving it's result from sys.getwindowsversion().platform_version. I'm not sure if the result is intended or is a bug but Microsoft seems to claim in this post https://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_install-insiderplat_pc/wrong-version-of-kernel32dll-in-win10-insider/b0053ba0-f6e5-48f1-86e3-ddac28d6c4eb that both builds are same just the versions are different.
