Demo virtual machine can be downloaded from the following location.
The virtual machine has Num Lock key enabled by default, which requires the user to manually disable everytime VM starts.
To disable the Num Lock permanently go to the registry [regedit] and navigate to [Hkey_Current_User\Control Panel\Keyboard] and change the [InitialKeyboardIndcators] key to '0'.
If the above step does not work as often when rebooting machine registry key is reverted back to original state, to fix this the other way is using standard Windows command go to [Start\All programs\Accessories\Accessibility\On-Screen Keyboard] and then un-check the 'nlk' key.
