windows vista

hello friend As you know Security of Vista is very tight so you have to format your computer or to ask a professional hacker but also I know a trick I have tried it on XP.You can try it may be it work. Just start your computer when login screen comes press (ctrl.+alt.+del) two times and a new login screen will come. Here type username as administrator and password field blank and your system will start now it is admin mode so you can change your password. Enjoy and happy mylotting
