I didn't really associate with it C (I didn't use it from that language); it seemed just another set of WinAPI functions from the docs, all of which used C-style declarations. It seems to be still present on every Windows OS, so I don't think it's going anywhere. msvcrt.dll is also used by gcc/tdm on Windows as well as tcc, for building programs. If it suddenly disappeared, then quite a lot of programs would stop working... ... including gcc.exe and tcc.exe which themselves both import msvcrt.dll.
