I tell you the matter again windows XP has many types of co version that is like XP home, or like XP professional. They are little bit different from each other.
Though the other version I mean co version of XP have that kind of option but the home and professional not have this kind of option in normal mode but there is good news for you it is about the safe mode.
You have the ultimate option of log in to the administrator. So when you start your pc and press “f4” button. You see a black window come up there at the top you will see the option safe mode. Go there and you will find your path.
