Android Emulator no longer works Windows 10 Anniversary

[CMJ]

Hi,

I am a developer using Android Studio with the Android Emulator.
The emulators worked just fine with GPU host acceleration(GLES 2.0).
But since I updated to Windows 10 anniversary (build 14393.5) HW accelerated GPU stopped working.

The error message from Android Studio / AVD Manager:
init: Could not find wglGetExtensionsStringARB!
getGLES1ExtensionString: Could not find GLES 1.x config!
Failed to obtain GLES 1.x extensions string!

It's unusable in software emulation.
DELL XPS 9550 with DELL D3100 docking station.
I have tried the latest DisplayLink drivers; 06-Jul-16, 8.0.480.0 but still no luck.

Any ideas?
