So I got bored and wrote just some send() keys to invert Windows 7 desktop. I'm looking for an easier way and that would work on main Windows OS's (XP, Vista, 7)
Windows 7:
Send("#r")
Sleep(500)
Send("desk.cpl")
Send("{ENTER}")
Sleep(500)
Send("{TAB 3}")
Send("{DOWN 2}")
Send("{TAB 7}")
Send("{ENTER}")
Sleep(1000)
Send("{LEFT}")
Send("{ENTER}")
Send("!{F4}")
