Windows 10 Driver issues?
How do you fix issues with drivers when you upgrade your bootcamp to Windows 10? I am having issues with the Multimedia Driver. How can you rectify this? Is Windows 10 just not able to be on bootcamp at all?
there is no support for windows 10 in bootcamp
your best bet is to try installing the window 8.1 drivers
Boot Camp Support Software 5.1.5640
or
Boot Camp Support Software 5.1.5621
or wait until apple make a new version of bootcamp which support win10
