Thanks, for that piece of information focher:
"The two devices you see are for the Intel Active Management interface and the Intel Management Engine interface."
Once I knew what they were I was able to download the correct files from Dell. They did not automatically install (when run they both failed). But than going back to the device manager and selecting update drive and the location of the files, both installed and are working correctly.
The computer was running fine, but I do not like to leave thing unresolved.
