My daughter's computer locked by Microsoft saying "sign-in option is disabled because of failed sign-in attempts or repeated shutdowns" This is despite her using her correct password each time she goes on and is a lie! She is in tears because of Microsoft's arrogance and prevent from accessing her homework. Locking computers people own and have their own copy of Windows on is completely unacceptable and just shows arrogance and greed. Clearly government action is required to control this appalling company. This needs negative stars. I have better things to do then resolve problems microsoft decide to cause.This is happening each time her login is required !!!
