That's because it's causing issues for windows 7 users. 8/8.1 is fine.

Well I had issues straight away when I installed the AMD Omega driver.
I had already installed that windows update previously and after installing the new driver, I had a BF4.exe error when trying to start the game.
I uninstalled the windows update in question and after running DDU and reinstalling the Omega driver it was ok, so I'm not sure what was at fault.
Windows 8.1 Professional
