Occasionally, I have a program that freezes, and then refuses to give the screen to me so I can use the normal task manager to kill it, and no amount of alt-tabbing or ctrl-alt-deleting can get rid of it.
In old versions of windows, this was a situation where I said goodbye to any unsaved work and hit the power button. However, with windows 8, I have found that I can still access the start screen - and this gives me a significant amount of hope that there is a way to kill a program from the start screen.
Unfortunately, my searches for task managing apps on the windows 8 app store are fruitless, because as you might or might not expect, todo list making apps are all that come up (people really spend more time organising their todo lists than killing unresponsive programs??). Also a search for a start screen based command line turned up nothing but command line dictionaries.
Is there a way, through a specific app or other wise, that I can kill a program that is running on my computer solely using the start screen?
