I noticed today my windows laptop wasn’t auto enabling num lock on boot, this was very annoying so I found this little bit of code to solve that:

1. Click Start, click Run, and type regedit to open the Windows registry editor.
2. In the registry, open the below folders.
   HKEY_CURRENT_USER\
   Control Panel\
   Keyboard\
3. Within the keyboard folder, you should have a string value named "InitialKeyboardIndicators" with a value of 0, 1, or 2. Below is the explanation of each of these values.
   0 = Num Lock is turned OFF after the logon.
   1 = Disable Num Lock.
   2 = Numlock is turned ON after  the logon.
