    Prior to installing Fiddler 4 on my computer, Cortana, Windows Store, Updates, UWP Apps, etc... Were all capable of using the internet flawlessly. However, after installation whenever Fiddler 4 is not open/active my entire OS is virtually destroyed by being unable use the majority of features.

    I reset all system policies, ran Windows SFC/DISM, malware/virus scans, and registry integrity checks - all clear. I have also reset the Wininet Catalogs, Set Manual DNS, Flushed DNS Cache and renewed IPConfig. There are no proxies defined under Windows Settings, IE Explorer, nor Control Panel.

    Thus I removed Fiddler 4 with a complete uninstall expecting it would undo the damage it has caused, needless to say, it has not resolved the problem?

    (Even running another proxy does not work, it is truly bound to this malicious like application.)

    Hello Jordan,

    I am sorry to hear about your experience. In order to check if it is Fiddler's fault, we need to reproduce the problem on our site. Could you please provide us with the exact Windows' version and build numbers on your computer. You could find them out by typing 'winver' into the Windows' search box next to the Start button. We also need the exact version of Fiddler which you installed and how you installed and if you had an older version of Fiddler beforehand. Please, let us know if you are using any third party Fiddler extensions, as well.
