Running W7 Home Premium on Dell desktop. Had trouble today for the second time trying to install update KB4056894. Update screen shows successful download and restore point created, then a blue screen with a row of numbers and no further activity after a long wait. Used manual power button on computer to shut down and restart, then went through an elaborate and lengthy process using System Restore and Startup Repair to get back to functionality. At multiple points, got message "computer unable to restart" but on both occasions I found a restore point that got me going. Although the computer seems to be ok, I did get a message box that Computer Restore did not work. Anyone else having these issues?
