I think i found the problem :

i installed the juny2010 directx package, tested the DX9 text example fullscreen on windows 10 without crash.

I noticed the sound is not longer in use for newer windows versions, and there are 2 other sound things like XNA or something ?

So i guess the problem is in the sounds, i will recompile my game without sounds and test in win10 again, then i go with the newer audio librarys.

Confirmed : i removed all wavefiles and removed coinitialize, no crashes.
