I tested on Windows 10. You're right, I don't see it in 2k3 SDK, in SDK 
10.x they have new macro for this, everything still guarded with XP 
version. For our implementation it's enough to have a fixme for now, if 
it's not working with Win7. If you can't test on Win10 right away, feel 
free to send me your test program.
