System DLL error on every log in.

Every time I log in on my Microsoft Surface Pro 6, I see the following error:

It says, "You are attempting to open a file of type 'System File' (.dll)".

The "OK" button is greyed out, and there is no way to find out what DLL file is being requested, or by what program. If I touch any part of the interface, even just clicking anywhere on the desktop, this dialog box disappears.

I did a system scan for viruses or malware, and the results came back that there was no malicious software found. Which doesn't mean there isn't malicious software, but so far it seems this might just be an error of some kind.

How do I diagnose and fix this problem? I have not seen any other problems, but I want to make sure this is not symptomatic of a deeper problem.

By the way, I tried contacting Microsoft Support, but the support chat function is currently not connecting to any people for some unknown reason.

    In the Search field lower left, type:

    CMD  Right click on CMD  Click Run as administrator

     Type in at the prompt OR Copy and Paste these one at a time : (Hit enter after

    each)

     Dism /Online /Cleanup-Image /CheckHealth

     Dism /Online /Cleanup-Image /ScanHealth

     Dism /Online /Cleanup-Image /RestoreHealth

    When this completes, run the  System File Checker utility: In the Cortana/Search field, type:

    CMD

     Right click on CMD  Click Run as administrator

     At the Command Prompt, type:

    sfc/scannow

     This checks for any integrity violations

     Restart your system

    Thank you for responding.

    Strangely, when I rebooted before trying your suggestions, I did not see the message I had originally reported.

    Nonetheless, I ran the commands you listed, and there were no errors or problems reported. Hopefully this means all is stable on my computer.

    I remain a little concerned that there was no obvious action that led to the message being removed. But, I suppose I can consider this closed for now.

    Just this week (coincidence?) I had exactly the same problem  on my Dell XPS 15.  I followed Barb's instructions and the problem has disappeared. Thanks, Barb.
