Program for setting global hotkeys on Windows 7?

Autohotkey. Nothing else.

Simple, yet very powerful, syntax, good scripting, lightweight, so on. It's almost perfect, and can do just about anything you ask of it.

Slight niggle with win7: It must be run as administrator to have hotkeys functioning in elevated apps.

In Windows 7, it's possible to start programs which have been pinned to taskbar by pressing Win+1, Win+2 etc. hotkeys. So Windows 7 has built-in hotkeys for starting up to 10 programs.

If the program is already open, then Win+<number> changes the active window or minimizes the only open window. Win+Shift+<number>, Win+Alt+<number> and Win+Ctrl+<number> also do some things.
