Keep in mind that AHK is not built for the command line, so we must call the WinAPI directly. <lang AHK>DllCall("AllocConsole") ; Create a console if not launched from one hConsole := DllCall("GetStdHandle", UInt, STDOUT := -11)

VarSetCapacity(cci, 8)  ; CONSOLE_CURSOR_INFO structure DllCall("GetConsoleCursorInfo", UPtr, hConsole, UPtr, &cci) NumPut(0, cci, 4) DllCall("SetConsoleCursorInfo", UPtr, hConsole, UPtr, &cci)

FileAppend, Cursor hidden for 3 seconds..., CONOUT$ ; Prints to stdout Sleep 3000

NumPut(1, cci, 4) DllCall("SetConsoleCursorInfo", UPtr, hConsole, UPtr, &cci)

FileAppend, `nCursor shown, CONOUT$ MsgBox</lang>
