Hi,
To remove the error, first download Autoruns:
https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns
- Unzip autoruns64.exe, then right click and run as administrator.
- In Autoruns Options, make sure both "Hide Windows Entries" and "Hide Microsoft Entries" are unchecked, and "Hide Empty Locations" should be checked.
- In the Quick Filter box enter: rundll
- Click on each entry found, then look to the bottom of the Autoruns window and you should see the complete file path
- If the path references RnbmrWebPEndrsrv.dll, right click on the entry and delete
