Weird behavor in Edge - Appending &PC=DCTE to end of URL

[upsidedown]

I recently upgraded to 14291, and now whenever I use Edge and type in a URL to the address bar it adds a &PC=DCTE to end and will not find the page. I have searched Bing and Google and can not resolve this. Any help is appreciated.

Experiencing the same issues. Trying to diagnose.
Do you happen to have a Dell/ Alienware PC?

It is a Dell Inspiron 3847. Reset did not work. I finally reinstalled an original ISO of W10 10586.1511 to get things back to normal!
