Automatic Windows Update caused my SP2012 Dev enviroment to break today!

The Security Update KB2756920 caused every SharePoint site to error out with “Object reference not set to an instance of an object.”  on Microsoft.Office.Server.Administration.UserProfileApplicationProxy.get_ApplicationProperties()

other symptom's where with the Security Token Service:

An exception occurred when trying to issue security token: The requested service, 'http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc/actas' could not be activated. See the server's diagnostic trace logs for more information..

Trying to acces the service would give:

Method Not found: "System.String System.ServiceModel.Activation.Iis7Helper.ExtendedProtectionDotlessSpnNotEnabledThrowHelper(System.Object)"

Apparently it only happens to windows 2008 r2, with no SP1 installed.
