Ok, so I couldn't get the Drivers to revert to Microsoft's and Intel's drivers were broken. I tried uninstalling the drivers via the exe and via device manager and in safe mode. NOTHING.
Download PsExec from here.
Unzip and place in Root of C: Drive.
Now open CMD with Admin Privileges and run the following:
C:\PSTools\psexec -i -s regedit.exe
This opens RegEdit in a way that you can do serious damage! Be Warned
Now delete all keys under >>
Now use Installation Executable to uninstall Intel Drivers & Reboot.
You should now see the BT stack working and back to Microsofts crap drivers, if you'r like me and just trying to get back to Toshiba BT Stack, read here.
