I recently installed Windows 10 Pro on my iMac, 27 inches, 5k, all the bootcamp drivers works perfectly, except by Amd Radeon R9 M295X driver, the driver for this does not work, and AMD is like it does not care, I have not found any solution for this.
The windows update seems to found an update for this driver, but when I try to update I am getting an error "Advanced Micro Devices, Inc. driver update for AMD Radeon R9 200 Series - Error 0x80070103", I have not found any solution for this error.
I share this with you, and I hope tha someone have a solution, or at least, maybe, AMD take care about this.
this is the driver in the device manager:
and this is the error when trying to update:
Regards, and sorry by my english.
