Windows 10: Windows wallpaper virus?

I am having very strange experiences: my networked desktop changed wallpaper to a visitors laptop logo and photograph, for background wallpaper.The image was not saved on my PC, and was not downloaded...The only link we have was WiFi network and the PC's logged into chrome (but not the laptop)

I changed the desktop again and I ran a scan with Malware bites and Defender with zero results.


It's as if their wallpaper jumped to each of my PC's in the network or logged in to the same account. it even happened to a PC external to the network but logged into Chrome and windows email


When i spoke to the guest who used their laptop they said my wallpaper landed on his desktop


All PC's virus checked and Malware checked to no avail


Please help


Thanks
