Тема: AHK: Установить поверх всех окон в Windows 10 с помощью SetWindowBand

Вот ссылка на этот api, работа очень хорошего реверс-инженера ADeltaX.
https://blog.adeltax.com/window-z-order-in-windows-10/
Чтобы вызвать SetWindowBand, нам нужно заинжектить dll в explorer.exe и либо установить хук на SetWindowBand и показать стартовое меню, либо установить хук на NtUserEnableIAMAccess и перехватить iam ключ.
https://blog.adeltax.com/how-to-call-setwindowband/
Вот скрипт, который инжектит autohotkey.dll и устанавливает хук с помощью minhook.dll
Нужно скачать minhook враппер от tmplinshi.
https://github.com/tmplinshi/MinHook-AHK
И запустить следующий код из папки с примерами.
Нажатие f11 установит самый высокий window band в активное окно, равный osk или окну лупы.

SetWorkingDir %A_ScriptDir%
#NoEnv
#Persistent
#SingleInstance Force
if (A_Is64bitOS && A_PtrSize = 4)
{
   Run, %A_AhkPath%\..\AutoHotkeyU64.exe "%A_ScriptFullPath%", %A_ScriptDir%
   ExitApp
}

ourBand := 2   ; ZBID_UIACCESS

   hook1 := New MinHook("", address_SetWindowBand, "SetWindowBand_Hook")
   hook1.Enable()
   return

   SetWindowBand_Hook(hWnd, hwndInsertAfter, dwBand)
   {
      global hook1
      return DllCall(hook1.original, "ptr", %ourHwnd%, "ptr", 0, "uint", %ourBand%)
   }

               break 2
            sleep 10

      }
   }

Пример c перехватом iam ключа.
После запуска скрипта следует дождаться сообщения iam key received.
После чего понажимать f11, f12, которые меняют band активного окна:
