Until then, you can get back into windows by continuously hitting alt-ctrl-del until windows allows the task manager to start. It will give the same error about the task manager most likely. Just keep hitting it and don't worry about the popup. Once it is up you will do the same thing with starting a new task and typing explorer. Once the computer is started, don't do anything with it!
