The certificate is installed for the user that works with Fiddler Everywhere. To remove it, follow these steps:
1. Open the "Manage User Certificates" control panel window. The easiest way to do this is from the Windows Start Menu - search for "manage user".
2. In the window that opens, expand the "Trusted Root Certification Authorities" item and select "Certificates". In the list on the right, find the certificate with a name "DO_NOT_TRUST_FiddlerRoot".
3. Delete the certificate. There should be one or two prompts when you try to delete it - you must answer "Yes" in both cases to fully remove the certificate.
Thanks. It actually turned out that I blamed Fiddler when I instead should have blamed the latest May update from Microsoft which apparently broken a lot of things for many. As we all know, Fiddler can sometimes be the reason for some connectivity problems with proxy setup etc but in this case it wasn't.
BTW, you should add these instructions to the documentation as the new Fiddler Everywhere does not seem to have the option to remove the HTTPS cert which I recall that the old version had.

Hello,
I will log a feature request to have the remove option in the Fiddler Everywhere HTTPS settings (like in Fiddler Classic) and also I will forward this thread to the appropriate people for the Fiddler Documentation.
Regards,
