It's not only once that we have had a problem with a certain window which doesn't seem to want to be closed and remains frozen on screen and not responding to our click in that upper-right cross. But now and thanks to Task killer, a free Windows application, that will not be a problem anymore. Task Killer will show you a list of the processes running on your system, ok, Windows also does it, but Task Killer is different, because it is really effective when stopping those processes. When it is running you'll see a tiny icon in the system tray and if you have any problem with an application, just click on that icon, you'll see the full list of processes, choose the one you want to finish and kill it. Finally, we should highlight that it is free, so it can be really useful if you usually have problems with frozen windows.
