i have the same issue. spectre laptop is locked due to alert from microsoft for security risk. i locked the laptop. now I can not get it reopened. all the links and directions you have given are incorrect and do not work. if you can not get into your computer because it says it is not connected to the internet (which it is) and it says administrator has to unlock (which I am, and cannot do) there is no way to get into the laptop because it will not accept the pin or finger print. so telling me to change a password when I can not even get into the laptop is ridiculous and more than a little frustrating. there is no unlock button as microsoft has stated on find my device.
so tell me please how to unlock my laptop here is what i see:
provide a pin
next screen: administrator has restricted sign in make sure device connected to internet (it is) have admin sign in first
there is no way to get into laptop.
why does microsoft not have a solution to this problem?
