The only stable interface on Windows are the documented functions from kernel32.dll, user32.dll etc. Libc is a compatibility layer above that, that Microsoft invents a new incompatible distribution mechanism for every 3-5 years. It’s pure DLL hell unfortunately.

Edit: Not even the DLL name of Microsoft’s libc is stable (msvcrt140.dll etc.), leading to all kinds of wild goose chases when trying to run old binaries.
