Old laptop dell, Core2 Duo. Windows Update still hasn't offered the Anniversary Update so I downloaded the installer (Windows10Upgrade28084.exe)today, and installed. After which, whenever waking from sleep, the lock screen would be totally unresponsive to keyboard and mouse; only solution was hard power-off. Oddly, lockscreen worked fine on initial startup. The wife won't put up with this, so I rolled back.
But I do want to eventually get to the Anniversary Update. When I try again with AU, what should I try to fix the frozen lock screen problem?
