ActivateByNum adds task-switching hotkeys on XP and Vista -- like on Windows 7. You just press the Win key plus a number to switch to the nth program showing on your taskbar. For example, if your taskbar shows NotePad, Word, Firefox, and Excel in that order, pressing Win+1 would switch to Notepad, pressing Win+2 which switch to Word, etc. If you like to keep your hands on the keyboard, this little utility is very nice.
Operating System: Windows XP, Windows Vista
