Ever since I briefly installed and uninstalled a face/fingerprint recognition program called True Key, I get a Windows Live error message at startup, saying there is a problem that caused parts of Windows Live ID sign-in assistant to be disabled, which may have been caused by a recent installed program. The message directs me to a Microsoft URL that leads to a dead end. I don't use Windows Live any more and have uninstalled it, but the error message keeps popping up every time I sign in. How can I get rid of it?
