|Re #11 - Not a virus. You should be able to uncheck it again but you have to go through each step given in #10 once more or the setting will be unavailable. The Power button setting should have no bearing on this.|
There is a chance this shut down problem will fix itself with the next cumulative update or features update.
"And I can't do a Restart either"
Do you mean that if you go to the Windows icon you can't get the computer to respond to a restart? There are two ways to do this, left click then the Power icon or right click via "Shut down and sign out". If you haven't been able to restart try the other method.
Always pop back and let us know the outcome - thanks
