Win 8.1 with virutalization enabled on box with RAlink bluetooth for HP envy 700-056

I wrote about this issue earlier at http://fetchmytip.blogspot.de/2014/03/issues-with-wp8fullexe-windows-phone.html. 

Problem:
Installed windows 8.1 upgrade with virtualization enabled and box rebooted but never finished the install!  This occurred when I was trying to do windows phone development with the WP8 SDK.  The phone emulator requires that virtualization is enabled.


Solution:

The Bluetooth driver for the RAlink 3290 board was for win 8 and not win 8.1 each time the reboot occurred it would attempt to load the driver and prevent the reboot.  The solution was to locate the correct drivers. 

Mediatek 802.11 Wireless LAN Adapter Driver
Type: Driver - Network
Version: 1.00 (19 Sep 2013)
Operating System(s): Microsoft Windows 8.1 (32-bit), Microsoft Windows 8.1 (64-bit)
File name: sp63302.exe (38 MB)

Type: Driver - Network - Mediatek Bluetooth Software Driver
Version: 2.9.19.0 (22 Oct 2013)
Operating System(s): Microsoft Windows 8.1 (32-bit), Microsoft Windows 8.1 (64-bit)
File name: sp64041.exe (89 MB)

Installing both still did not solve the issue.  What is weird is that once I uninstalled the drivers for the Bluetooth device the virtualization started to work.  Since I do not need the Bluetooth device then leaving it disabled is fine and will allow me to do WP 8.1 development!
