Windows 7 Networking Tutorial

In this tutorial we will present a step by step guide of internet sharing in windows 7 homegroup network.

Sharing allows us to use a single internet connection across the network. We need not to buy a separate internet connection for each PC. Just buy a single connection and share it on all PCs.
