Sharing an internet connection on Windows

We have couple of computer devices like laptop or desktop with only one internet connections. In that time if we need to share the internet connection with multiple devices. you can turn your computer into a wireless hotspot (or wired router) for other devices nearby, Note that this requires your host computer to be connected via wire to the Internet modem (DSL or cable modem, for example) or use a cellular data modem on your computer; if you want to share a wireless Internet connection with other devices, you can Turn Your Windows 7 Laptop into a Wi-Fi Hotspot using Connectify.

Optional: If you want other network users to be able to control or disable the Internet connection, select that option.

You can also optionally allow other network users to use services running on your network, such as mail servers or web servers, under the Settings option.
