Proxy free Windows xp/7/8 and Mobiles!

All the methods mentioned below are ethical and your institute should ideally allow them as they need your proxy authentication at some point or the other.

1. CC Proxy

  • Open CC proxy as administrator.
  • Go to Options. A configuration window pops, select your ip from the drop down (Ex: in my case) and check the checkbox right to it
  • Go to advanced (in options)->cascading tab->enable cascading (select all)
  • Enter your server details (Ex: server:, Port : 80) and authentication
  • Open proxy settings in Internet explorer->enter your proxy server as your ip address ( in my case), port as 808 for all but SOCKS. Enter 1080 for SOCKS
  • Open command prompt as admin user->type this. (Type cmd in search and right to open as admin)
  • Enter this ‘netsh winhttp import proxy source=ie‘ without quotes ofcourse and enter
  • And your DONE!!
For frequent ip changers: Goto Accounts and set,
                                        Permit category: Permit only
                                        Auth Type: IP Address
Select New (in same window) -> Enter IP Range as ‘’. Ensure Enable and IP Adress are checked.
Now instead of entering ip address in browser or other applications, enter

This is usually helpful to give an authentication free proxy to mobiles and other gadgets. If it didn’t work for you as is (I know it doesn’t for Windows 8 users), Download the below application and follow the steps. Mobile users scroll down for settings.

File name : ‘ccproxysetupfree7.2 .exe’
NOTE: Though it’s a paid software. You can use the free version without registering.


This one helps you run your Metro apps (Windows 8) without proxy pains!!
This app can’t do the job by itself. You need CC proxy setup done, for it to work

  • Open the app->After a copy process, press close->A window popsup->Click exempt all->Save changes and you are done !
  • A restart may be needed in some cases.

Download from!/Downloads
File name : ‘EnableLoopBackUtility.exe’


I own no credit about this video or method. This routes all you PC traffic through it with no need of settings in other apps! You can use everything as though you don’t have proxy! Its a paid app btw ;)

Download from!/Downloads
File name : ‘ProxifierSetup.exe’
NOTE: Its just the setup file. You need to either buy it or use a crack which you have to download seperately. IITB ppl can search for crack on DC as ‘netmon proxy’

-Here is a video which guides you. This video made for IIT Bombay proxy server. You can do it similarly for yours

Windows 8 tip
It has been noticed, quite often, that windows 8 metro apps won’t work even after following the above steps. Just consider yourself one of those unlucky souls and try this,
  • If you see exclamation mark on your LAN connection, right click on that icon and try ‘Troubleshoot problems’. It may work if the mark goes away.
  • Still not working ? You hit the jackpot :P It may take a couple of restarts. Don’t panic ! It will work on someday. There is nothing much I can comment on this particular behavior.
Mobile settings 
If you running on Android 4.0 or higher (works for windows phones also) and want to use institute LAN speeds without having to root follow this.
  1. Setup CCProxy as mentioned above
  2. Create a WiFi hotspot, either using connectify or without any third party software from here
  3. While connecting to the hotspot created above, go to advanced options while entering WiFi password
  4. Change proxy settings to manual and for host, enter <ip> you gave in CCProxy setup and the port as 808.

Google Play Store now has Smart Delta App Updates [Download updated parts of apps only]

At Google I/O the company announced that the Google Play Store would be getting the ability to offer delta smart updates for apps, so that you wouldnt have to download an entire app again whenever it got an update.
This is a move that will save tons of people a lot of data, especially considering scenarios like how a game like Asphalt which weighs in over 1GB, can get an update with just two new cars, for which you will have to download the entire 1GB game update. Saving time and bandwidth, the Play Store will only download the actual changes of an app instead of the entire program or game. Very useful if you’re on a limited data plan.
Smart app updates is a new feature of Google Play that introduces a better way of delivering app updates to devices. When developers publish an update, Google Play now delivers only the bits that have changed to devices, rather than the entire APK. This makes the updates much lighter-weight in most cases, so they are faster to download, save the device’s battery, and conserve bandwidth usage on users’ mobile data plan. On average, a smart app update is about 1/3 the size of a full APK update.

I’m still running tests on other devices. However we strongly believe that it works fine on all devices

Data usage warning:

Data warning!

MDroid fetches contents by going through the required Moodle webpages. So, it will have a slightly heavy data usage depending upon your usage
Don’t panic! We have a work around for that!

Work around

It is highly recommended for the users to make use of the Institute Internet speeds/Wifi connection on your phone
How? very simple! Just follow below steps

  • Lemme tell, you do NOT have to ROOT your phone for this
  • Connect to any of the institute Wifi’s or create one for yourself using connectify
