bootcamp drivers Win10 freeze in Realtek audio

Hi There,

I did a bootcamp install of Windows 10 (Release 1511) to my MacBook Pro Retina 13-inch (Late 2013) and I cant install Bootcamp Drivers. After finishing installing Windows when Bootcamp Drivers are automatically launched, it freezes in Realtek Audio. I tried with different versions of Win10 and still having the same problem (see attached img)

I already had a Win10 Bootcamp installation that was running perfectly until I began to have issues with the SD card driver showing not properly enumerated in Windows (I didnd had any issue with the SD card in OS X) So I decided to wipe out bootcamp and reinstall everything however now I cannot get bootcamp drivers to complete installation and I don't have the Keyboard backlight or the Apple Fn keys working (Brightness, Volume, etc)

Regarding the SD card not enumerating, this is an intermittent issue, sometimes it enumerates correctly (and the Startup Disk options shows right away when restarting an holding the option key) and other times it takes like 3 minutes to give the Starup Disk option and I know for sure the SD will not be available in Windows. However in OS X, My SD card works perfectly. This happens with either a card on the slot or not.

Any input on this issue will be appreciated.

Any ideas why this is happening? The Realtek screen its been there for like 5 hours and nothing change.

Regards
