At least three ways. Pick your flavor: [Notice I have edited one of the 4 fixes mentioned in this link. There seemed to be some debate on whether the registry keyboard values tweak functioned, beyond a reboot. In other words the edit worked for that windows session only and upon a reboot was restored to prior behavior. I assume this value was being set and controlled by some setting outside of the registry. In other words that outside *.ini controlled the registry value not the other way around. This shouldn't effect you one or the other it only applied to win- XP/2000.] http://www.annoyances.org/exec/show/article01-001
NOTE*Intellipoint mouse may complicate ordinary tactics.
====For the Archives=======
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 (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.
