Also with Windows 7 and lower Windows OSs using Virtual router plus you are able to create a hotspot. When installing in windows 7 you may face some issues.

Some common issues:
1. Virtual Router Could Not Be Started

•  Close Virtual router
•  Go to command prompt. 

                     Go to START, enter "cmd", then press "ctrl + shift + enter" to open command prompt as administrator. If not right click and select open as administrator.

• Copy paste following two commands into command prompt, one by one.

netsh wlan set hostednetwork mode=allow ssid=myNetwork key=password

netsh wlan start hostednetwork

2. The group or resource is not in the correct state to perform the requested operation

In cmd try the following command:
netsh wlan set hostednetwork mode=allow

However, I could not get this to work in Windows 8.
