• Guest Additions of version 4.1, 4.1.2 and 4.1.4 for Windows Thus VirtualBox WDDM
Video driver may be installed and kept in guest system if Guest additions uninstallation is performed. This is caused by a bug in Guest Additions uninstaller.
To solve this problem, one should uninstall the VirtualBox WDDM Video driver manually. To do that open Device Manager, and check whether the Display Adapter is named “VirtualBox Graphics Adapter ..“. If no - there is nothing to be done. If yes - right-click the VirtualBox Graphics Adapter in Device Manager, select “Uninstall”, check “Delete the driver software for this device” and click “OK”. Once uninstallation is done - in Device Manager go
to menu “Action” and select “Scan for hardware changes” to make the proper (Windows default) driver be picked up for the Graphics adapter.
