Duke can't get his Windows screensaver to activate. He can preview it, but it doesn't engage on its own. Leo says that there has to be a setting in the power options that are preventing it. It may be "wake on LAN" in the BIOS that's preventing it from going to sleep. So get into the BIOS and make sure the wake on LAN is turned off. Leo also suggests checking to see if a third party screensaver is causing a conflict. R/C desktop - personalization. Windows Key + L will also turn on screen lock. That could turn on the screensaver.
Ron has a TV that is an "Amazon Edition." Recently, it started showcasing his photos as a screensaver. Leo says it may be showing your photos that are backed up to Amazon Photos. Or maybe even your Google Photos. If you're an Alexa user, it may be a skill that Amazon recently added. Can he opt-out? Leo says you can probably disable it in your TV's menu settings. Or it could be in the Amazon App. It could also be the Roku. There are apps in the Roku that picks up your photos. There's a slideshow setting in Roku that could be enabled.
