 Not really.
DLL that supports newer feature has different name - VCRUNTIME140.dll
And choice of DLL version is not directly related to the version of
Windows.

Well, both tcc and mcc (my product) import msvcrt, not that runtime file, and printf/zu works.
You can test it directly using the program below if you like.
If you think that the OS craftily substitutues vcruntime140.dll in place of msvcrt.dll, then copy "c:\windows\system32\msvcrt.dll" to "fred.dll", to a folder where it can be found. Then change "msvcrt" beflow to "fred".
If %zu it doesn't work, then maybe your copy is old.
