Windows Me no longer supports the "NUMLOCK=OFF/NUMLOCK=ON" settings that could be found in "CONFIG.SYS" in Windows 95/98. To change this, open Notepad and copy the following lines:
if WScript version="5.1" then
shell SendKeys "(NUMLOCK")
Save and name the file as 'NUMLOCK.VBS' and save it to the 'C:\Windows\Command' folder then create a shortcut in the 'Start->Programs->Startup' group.
