Apparently the Dell Registration application was the culprit.  Once I removed it from my system, the popup errors stopped.  
Not sure if this is right board...if not, let me know and i'll repost. I recently started getting windows error messages popping up, where multiple messages (up to 5 or 6) display same info then eventually disappear. I get a "Windows cannot access the specified device, path, or file" error window.  it shows a path of  c:\program files\windowsapps\DellInc.DellDigitalDelivery_4.0.36.0_x64_htrsf667h5kn2\Win...but doesn't display the rest. I am not able to access that folder, even with admin privileges. I have uninstalled and stopped any 'dell delivery' apps.  I don't see anything in the windows logs to give me a clue (although I'm not an expert in the logs, but nothing jumps out).   1.  What is kicking this off so I can kill the app or process OR 2. What can be uninstalled to stop it?
