Windows set proxy

If you want to setup a a proxy in Windows, you can follow these steps:
1. Open Internet Explorer (I chose this browser because every Windows comes with it)
2. When you are in browser press Alt (to see the Menu bar)
3. Go to Tools -> Internet options -> choose Connections tab -> LAN settings -> check 'Use a proxy server for your LAN' and fill the fields 'Address' and 'Port'.
If you want to set advanced options click on the Advanced button and fill the fields that you need.
