A. The registry entry HKEY_CURRENT_USER\Control Panel\Keyboard\InitialKeyboardIndicators can be used to set the initial state of the Num Lock key for the current user. To modify the state of NumLock for the logon screen.
- Start the registry editor (regedit.exe)
- Move to HKEY_USERS\.DEFAULT\Control Panel\Keyboard (we are editing .default which is the profile used prior to logon)
- Double click on InitialKeyboardIndicators
- Set to 2 and click OK
- Close the registry editor
An easier way is to turn NumLock on and the logoff using Ctrl-Alt-Del Logoff which will preserve the state of Numlock..
