where can i find drivers for iphone 6 on windows 10? Itunes doesn't see it at all!

Try the troubleshooting steps in here.

iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support

Hi

Turn iPhone OFF

Connect lead to USB on your PC

Press & hold power button down DONT let go on iPhone

Connect lead to iPhone keep power button pressed down

Until PC sees iPhone .

You may need to do this a few times before it works.
