Change Internet Explorer Connections Settings from Registry


Okay, I seriously thought I already have this post uploaded in this blog, but it turned out I was wrong. I have kept this for a long time, and it helped me a numbers of times already so I reckon it will help others as well.

IE Connections. There are a few settings we can configured in IE Connections Settings such as :
  • Automatically detect settings 
  • Use automatic configuration script 
  • Use a proxy server 
  • Bypass proxy server for local addresses 
  • Use different proxy servers for different protocols 
  • Proxy server exception. 

For this post, I will list registry keys positions for each setting.
