Hey FK. I have had this problem going on forever and none of my close friends have had a solution. So I have a custom built gaming PC I purchased with Windows 7 installed. But when I attempt to open Internet Explorer or any web browser is comes up with "Unable to connect to proxy server" and I have never used a proxy server but when I went into settings it had one enabled. I do not understand when I uncheck the proxy server box it just goes right back to the original server. Any ideas on how to disable that?
