Is it possible to use face recognition to log in win XP?

From last three months I am using this features for my Lenovo laptops. I will definitely help you to use this feature. For the using of this incredible feature you must have a webcam that is installed in your computer. Now click on the start button. Go to the control panel. Now single click on the user account. Multiple options are appearing over there. Like the change password and change user account picture and more. Now search for the option of the face recognition password. If that option is displaying over there than only you can use this feature. They will save your face video clip for the recognition of your face. Please note down that do not use the face recognition software you have to use your laptop in low light or the darker light. Computer will not able to recognize your face in less light and you will be not able to log in on that condition.
