Eu tenho uma solução geek :-) Script em Python que passa por todas as janelas fora da tela e oferece movê-las para o canto superior esquerdo:
import winxpgui, sys, win32con
screen_width = 1920
screen_height = 1200
def WindowsListEnum(hwnd, data):
pos = winxpgui.GetWindowRect(hwnd)
left, top = 0, 0
if pos[0] < 0 or pos[0] > screen_width:
left = 10
if pos[1] < 0 or pos[1] > screen_height:
top = 10
if left or top:
print winxpgui.GetWindowText(hwnd), ',', pos, '->', (top, left, pos[2], pos[3])
if sys.stdin.read(1) == 'y':
winxpgui.SetWindowPos(hwnd, win32con.HWND_NOTOPMOST, left, top, pos[2]-pos[0], pos[3]-pos[1], win32con.SWP_SHOWWINDOW)
print "press 'y' to move the window, anything else to continue\n"
winxpgui.EnumWindows(WindowsListEnum, None)
Você precisa de Python e Win32all .
