I’ve been using Google Chrome since the beta came out to the public and I loved it since then. Recently I found out that Google Chrome doesn’t provide an user interface to enable or disable proxy server settings but is sharing Internet Properties settings with Internet Explorer. So if Internet Explorer is using proxy server, Google Chrome will use it also meaning both are sharing the same proxy server settings. Thanks Jhay for the tip! 

Here’s How to enable or disable proxy server settings of Internet Explorer without affecting Google Chrome and vice versa

1. On Internet Explorer click on Tools > Internet Option
   • You can also press alt button to show the menu toolbar 
2. On Google Chrome click on Settings (wrench icon) > Options
   • Click on Under the Hood Tab
   • Look for Network then click on Change Proxy Settings 
3. Copy the settings as shown on the screenshot 
   
   
4. Now, close both Internet Explorer and Google Chrome
5. then Open again, you’ll notice that you cannot browse or search the internet using IE and Chrome
6. You can fix Google Chrome not to use the same proxy settings by adding –proxy-server= in your Google Chrome shortcut. use this –proxy-server if the other one did not work on you. Thanks again Jhay for the tip
    
7. click the OK button then launch again Google Chrome 
8. verify now if  you can now browse the internet.
