While in Command Prompt (Admin) enter the following command:

 NETSH WLAN set hostednetwork mode=allow ssid=Your_SSID key=Your_Passphrase


Where the SSID would be the name you want to identify your wireless network when trying to connect a new device, and the passphrase is the network security key you want users to use to connect to your network. (Remember that the passphrase has to be at least 8 characters in length.)

 Once you created a Hosted Network, enter the following command to activate it:

 NETSH WLAN start hostednetwork
