I looked on the internet one more time and in the comments of a youtube video had my solution:  HKEY_LOCAL_MACHINE\SOFTWARE\Cambridge Silicon Radio\Harmony\Default "OSD" - > set it to "0" and restart computer.  I do not have the notification anymore. Thanks!
I have a XPS 8500 with a Windows 7 Home Premium OS, 64-bit operating system. I have scoured google like crazy for answers with no luck. It's not in Ease of Access options, I have no options for such in Display settings or Keyboard, nothing of my Bluetooth is causing it, and even various suggestions of registry edits do not apply to me.  I am at my wits end. I find the notification to be distracting. Is it possible for a specific Windows Update to cause something like this?
