Assume that you have a computer that has Windows Embedded 8.1 Industry installed. Additionally, assume that you try to set the NUM LOCK key as the breakout key on the computer by configuring the value of the following registry entry to 0x45:
HKEY_LOCAL_MACHINE \Software\Microsoft\Windows Embedded\KeyboardFiler\BreakoutkeyScanCode
Note The scan code for the NUM LOCK key is 0x45 in Embedded Lockdown Manager (ELM).
When you save the value, it is converted unexpectedly to 0x2D. After you restart the computer, the NUM LOCK key does not work as the breakout key. Instead, the X key now works as the breakout key.
Note This issue also occurs for other keys that you try to set as the breakout key by using a hexadecimal value.
