1. Enable Num Lock on the Windows 8 Logon Screen

Some user believes that there is a setting in Computer BIOS that num lock will not be enabled automatically on the logon screen. But let's think that you have enabled the user authentication while logon and your password will be in numerical. So, if you want to enter in the Operating System speedily you have to turn first Num Lock On then type, if in case you forget to turn on then password will be wrong. Here is the simple tweak to Enable Num Lock on the Windows 8 Logon Screen.
  • Open "run" (Win Key + R), type "regedit" (without quote) and hit enter.
  • After that one window will appear, as shown in below image.
  • Now Browse to this location: HKEY_USERS\.DEFAULT\Control Panel\Keyboard
  • Then edit the value of InitialKeyboardIndicators and set it to a value of 2.
  • Done successfully.
