Windows 10 - Critical Error - Start Menu and Cortana aren't working

The problem, happened again... but I solved it like this (at least until Microsoft solves the problem...)

I move the window down, so the tests can run as expected.

Maybe it helps someone

/**
* Moves 'Critical error' window down<br>
* @method erroCriticalErrorWin10()
*/
function erroCriticalErrorWin10(){
var propriedade = new Array("WndClass", "Name");
var valor = new Array("Shell_Dialog", 'Window("Shell_Dialog", "Critical Error", 1)');
var limite = 0;

objCriticalError = Sys.Process("explorer").Find(propriedade, valor, 20, true);
if(objCriticalError.Exists){
Log.Message(objCriticalError.Name);
objCriticalError.Position(0,1020,0,0);
}
}

There's a huge thread on this subject at Microsoft Community forums. I solved the problem by installing "Classic Shell"

Another solution is using Media Creation Tool as described in the above thread.
