    Removing interception certificates via Fiddler option "Remove Interception Certificates" only removes them from Personal and Trusted Root Certification Authorities. Certificate that is located in Intermediate Certification Authorities is not removed. This certificate is not trusted after using "Remove Interception Certificates" and has status "This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store".
    sigcheck -t[u]v doesn't show any warnings.
    Tested this on both Windows 7 and 10. Tried refreshing certmgr, restarting it, and rebooting machine with no success - intermediate certificate is still there.

    Thank you for brining this to our attention. I can confirm that after performing the Remove Interception Certificates action in the Fiddler HTTPS Options, the Fiddler Root Certificate still exists in the Intermediate Certificates and the Trusted Root Certification Authorities for the Current User Store. This has been added to our backlog.

    As a token of gratitude for your feedback, I have created a Public Bug Report and increased its priority by casting a vote on your behalf. I encourage following the item to receive status updates on the item. 

    Additionally, I would like to invite you to try Fiddler Everywhere which is the next version of Fiddler. It is cross-platform and has a completely refreshed UI. 

    In the meantime, please let me know if you need any additional information and thank you for your feedback.
