The spam came from inside the house: How a smart TV can choke a Windows PC

๐ŸŒˆ Abstract

The article discusses how a Hisense smart TV can cause issues with a connected Windows PC, including disappearing settings, keyboard problems, remote desktop issues, and taskbar problems. The root cause is identified as the TV generating random UUIDs for UPNP network discovery, which Windows then adds to its Device Association Framework, leading to various system problems.

๐Ÿ™‹ Q&A

[01] Hisense TV and Windows PC issues

  • Disappearing display settings
  • MIDI keyboard interface stopped working
  • Task manager would hang until force-closed
  • Video capture cards had trouble connecting
  • Taskbars on the PC disappeared and the PC refused to launch any settings panels

2. What was the root cause of these issues? The Hisense TV was generating random UUIDs for UPNP network discovery every few minutes, and Windows was adding these alternate Hisense devices to its Device Association Framework, which caused issues with Task Manager, Bluetooth, Settings apps, File Explorer, and more.
