Create Free WiFi Hotspot in Windows 7

Windows 7 has the ability to create wireless hotspots that allow you to share your pc internet connection.
You don't need any other software for this.
  •  First Enable Internet Connection Sharing on the network you want to share from network and sharing center.
    Enable internet sharing
    Internet Connection Sharing
  • Start cmd with Admin priviledges. Run cmd with CTRL+SHIFT+ENTER
  • Run the following command "netsh wlan set hostednetwork mode=allow ssid="techdorm" key="techd0rm" keyUsage=persistent"   #Change ssid and key to your like.
    Set netsh hostednetwork ssid and key
  • You should see "Microsoft Virtual Wifi Miniport Adaptor" when goto change adapter settings in Network and sharing center.
    virtual wifi
  • Then run the following command in cmd "netsh wlan start hostednetwork".
    start your wifi network
  • Now you should a WiFi network with ssid you choose above be able to connect to it.
  • To stop the network you can simply run "netsh wlan stop hostednetwork" 
I used to make hotspot using Virtual Router but started to give errors. This method is a bit hard to type every time. You can also create a .bat file which you can run with admin privileges. Microsoft should have made this just as simple as making Adhoc networks
