Make your Laptop act like WiFi Hotspot using Virtual Router
Virtual Router is a free, open source software based router for machines running Windows 7, Windows 8 or Windows Server 2008 R2. If a user wants to share his/her internet connection wirelessly with any other wifi devices such as Laptops, Smart Phones, iPod Touch, iPhones, Android Phones, Zune, Netbooks, Wireless Printers etc., then Virtual Router is an option. Moreover, the connection is completely secured as it is encrypted with WPA2 Encryption.

The software is completely ad-free and so it does not track the web traffic.
