I've successfully upgraded to Windows 10, and I'm using the latest AMD drivers at the moment, 15.7.1
I have a Mac Pro (2013) with the D700s.
The process, which actually is quite easy:
1. Download the latest driver (at the moment of writing 15.7.1), the AMD Omega 14.12 driver, and the official December Bootcamp Driver 14.301.
2. Make a new folder called "modded driver", which purpose explains itself.
3. Copy everytning from the latest driver to "modded driver".
4. Copy everything from the Bin64 folder of the Omega driver and overwrite everyting in the Bin64 folder of "modded driver".
5. Copy "InstallManagerApp.exe" and "InstallManager.dll" from the Bin64 folder of the December Bootcamp driver, and overwrite the corresponding files in the Bin64 folder of "modded drivers".
6. Now you are ready to install the driver. Just run "setup.exe" in the root folder of "modded drivers"
Now you should have new and better performing drivers installed, working perfectly with Windows 10.
If you have problems with the Catalyst software, which I had on the latest driver updates in Windows 8.1 (but not anymore on Windows 10), do the same process with an earlier version of the driver (15.5 worked for me), run the setup, and chose custom installation. Here you only chose to install Catalyst. Now Catalyst should work properly too.
Also, if you encounter any more problems using this method, you should uninstall the driver using "Display Driver Uninstaller", and probably delete everything AMD related in the registry (CMD+R, regedit).
Hope it works for you guys too! That being said, I'm really disappointed in the Bootcamp support, and the driver updates. I'm actually thinking about selling my Mac Pro, and building a pure Windows desktop, and no more AMD!!! I'm doing a lot of video editing in Premiere Pro CC, and have the experience have disappointed med, compared to how much money I put in it. No way I want to switch to FinalCut X (testet it with the trial). Also I game a lot, and that's not great in either OSX or Windows/Bootcamp, especially on new games that require driver updates with new profiles. I can play Borderlands 2 in 4K, but almost can't play The Witcher 3 in 1080p, even with the latest (modded) drivers.
Btw. don't blame me if you brick your GPU (which I don't think it's likely to happen, but I just have to say it).
