Let's see...
You have a main thread that starts thread A, then thread B.
Thread B depends on thread A being fully initialized.

Can thread A start thread B after it has initialized?
Can thread A set a signal that the main thread waits for?

hInitEvent = CreatEvent()
start threadA
 WaitForSingleObject(hInitEvent);
CloseHandle(hInitEvent);
start threadB

Then thread A does SetEvent(hInitEvent) after it has initialized.

All this puts the "waiting" code on the O/S side which is more CPU
friendly.
If you start thread A quite a lot, then you would want to move the
CreateEvent and CloseHandle outside the loop, and use ResetEvent()
just before starting the next thread A.
