У меня исторически работал сабж с помощью Windows PowerPro, но в 7 эта чудесная функция работать перестала »

Не тестировал в Win 7, но на XP для этой задачи прекрасно работает SwitchIt.

Можно ли такое реализовать с помощью AutoIt? »

Конечно:

Код:

#include <Misc.au3>

Dim $hUser32_Dll = DllOpen("User32.dll")

;Задаём языки циклического переключения (в том же порядке в каком они выводятся в списке ниже)
;Можно указывать как коды языков, так и их названия (см. список в функций _OSGetLangString):
Dim $sLangs_String = "English_United_States|Russian|Ukrainian"
Dim $aLayouts_List = StringSplit($sLangs_String, "|")

;"Ctrl + Shift + E" для выхода из скрипта
HotKeySet("^+e", "_Exit_Proc")

While 1
    Sleep(100)

    If _IsPressed("A1", $hUser32_Dll) Then
        _SwitchIt_Proc()
