Force NumLock to Behave 

Intended For Windows Me Windows 98 Windows 95

Ever since IBM introduced their enhanced 101-key keyboard with two sets of cursor keys, the NumLock key on most of our machines is turned on by default. Since some of us seem to prefer it off, while others prefer it on, there are several ways to change the default. However, many users have complained that Windows will not allow you to change this setting under some circumstances (such as having Microsoft’s old Intellipoint drivers installed). Following are several solutions to choosing the setting you prefer:

Solution #1:

• In any computer made since the late 1980’s, you can set the default in your CMOS setup. This screen, usually accessible by pressing Del, ESC, F2, or some other key when your computer first boots up, is where you also define your fixed and floppy drives, memory settings, the clock, and other system parameters.
• If the setting isn’t obvious, refer to the manual that came with your computer or motherboard for instructions on changing this setting.
• If you find that the Num Lock light obeys your wishes until Windows loads, at which time it is turned off or on, try one of the following settings.

Solution #2 (Windows 95/98 only):

• Include the command NUMLOCK = OFF or NUMLOCK = ON (depending on your preference) somewhere in your CONFIG.SYS file (on its own line).
• CONFIG.SYS can be edited with any plain text editor, such as Notepad. If CONFIG.SYS isn’t there, just create a new file.

Solution #3 (Windows 2000/XP only):

• Run the Registry Editor (REGEDIT.EXE).
• Open HKEY_CURRENT_USERControl PanelKeyboard (If the Keyboard key isn’t there, add it.)
• Double-click the InitialKeyboardIndicators value on the right. (If it’s not there, select New from the Edit menu, then String Value, and typeInitialKeyboardIndicators for the name of the new value.)
• Change the value to any of the following:
  • 0 – all indicators off
  • 1 – Caps Lock on
  • 2 – Num Lock on
  • 4 – Scroll Lock on

  Or, combine them by adding the corresponding values:

  • 3 – Caps Lock and Num Lock on
  • 5 – Caps Lock and Scroll Lock on
  • 6 – Num Lock and Scroll Lock on
  • 7 – Caps Lock, Num Lock, and Scroll Lock on
• Close the Registry Editor when you’re done; the change should take effect the next time you start Windows.

Solution #4 (only if you have Intellipoint installed):

• Run the Registry Editor (REGEDIT.EXE).
• Open HKEY_CURRENT_USER Control Panel Microsoft Input Devices Keyboard (If the Keyboard key isn’t there, add it.)
• Select New from the Edit menu, then String Value, and type NumLock for the name of the new value.
• Double-click on this new value, and type either ON or OFF in the box that appears, depending on your preference.
• Close the Registry Editor when you’re done; the change should take effect the next time you start Windows.
