Does Windows use std :: thread internally with PPL?

Is the implementation of Visual Studio 2015 std :: thread internally based on the PPL task system?

In my question, does it make sense to use std :: thread for several tasks, because they are already balanced in the common thread pool, or is it better to perform tasks using PPL tasks?

According to ( Which std :: async implementations use thread pools? ), This seems to be the case, but since the question is quite old, I would like to get an “official” answer.

Yes and no.

std::thread:
std::thread (thread )
_Launch (xthread ),
 _Thrd_startX (xthread ),
 _Thrd_start (cthread.c ),
 _beginthreadex (cthread.c ).

_beginthreadex, atlbase.h microsoft :

// _beginthreadex calls CreateThread which will set the last error
// value before it returns.
