Where are these system proxy settings? I noticed my connection has been slow for a while, then I checked the connection settings and was surprised there were set a proxy, but I cant see what exactly it is using.

Where can I check which IP it was routing the connection for me ?

Here is what I saw from Firefox (12.0) options:

As far as I can remember, it has always been "no proxy" and not "system proxy". Unless new firefox version has set that "system proxy" to default?

The proxy settings can be changed through:

  • Control Panel → Internet Options (inetcpl.cpl) → Connections → LAN settings

Is that really it? i mean, it opens the IE settings window... (i can change IE homepage etc through it too). – Rookie Jun 9 '12 at 17:49
Yes, I'm sure. The "Connections" tab controls the behavior of all programs using WinINet/WinHTTP libraries, and so most third-party Windows programs have chosen to honor them as well. – grawity Jun 9 '12 at 21:10
What if access to those settings is locked down (as in my case). Any way to determine the proxy settings through the commandline (for example)? – Dirk Gorissen Jun 12 '13 at 10:56
reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxyserver" – deizel Aug 27 '13 at 14:43
