Configuring Windows NT to enable the NumLock key
By default, Windows NT doesn't enable the [NumLock] key when a user first logs on to a Windows NT-based computer--and even if the user turns on [NumLock], Windows NT turns it off again whenever the user logs off if he is not a member of Administrators.
You can make the [NumLock] key stay on for non-administrative users by editing the Registry.
Note: You must either log on as the user or have the user log on and edit their Registry remotely. To turn on the [NumLock] key, set the following Registry value to 2:
HKEY_CURRENT_USER\Control Panel\Keyboard\InitialKeyboardIndicators
By default, Windows NT sets the InitialKeyboardIndicators value to 0 (which turns the [NumLock] key off).
You can turn on the [NumLock] key in the default profile so that all new users who log in to a computer have NumLock enabled by setting the following Registry value to 2:
HKEY_USERS\.DEFAULT\Control Panel\Keyboard\InitialKeyboardIndicators
