Runtime Broker 100% CPU Usage Issue – Update July 2019

Users have reported experiencing issues related to the Runtime Broker process with the Photos app.:

I do not use Photos app at all. I noticed lags in videos and games. If I am doing neither of those things, laptop fan starts spinning up at full speed. I checked and it’s always Photos app starting in background with one of ‘Runtime Broker’ processes consuming memory and CPU. It happens in on/off pattern. For a while CPU usage stays under 10%, then for a while it goes around 70-90% – cycle repeats. I fix it by opening-closing Photos app once. Everything calms down.
