“I got an old laptop with windows XP. I can’t log on to it as the admin account has password that I don’t know. What’s a tool I can use to crack or hack Windows password?”
Refer to the Windows password cracker, Ophcrack will comes to my mind immediately. It is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.
If you have forgotten Windows password for user and admin account, or purchased a used computer and it requires a password, Ophcrack will usually be able to hack it. It supports Windows 7/Vista/XP. The following steps illustrate how to crack Windows login password by using Ophcrack.
1 Download the Ophcrack LiveCD iso (~416 MB) from Ophcrack official website.
2. Burn the iso file to CD by using an image burning software.
3. Put the CD in the disc drive of the computer you want to crack the passwords of.
4. Boot the computer from the disc.
5. Save and exit BIOS setting and Ophcrack will initiate by itself.
6. The logo screen should appear, at which you should hit enter. Text should scroll down the screen, and eventually you will have a graphical interface pop up, with the one and only window (Ophcrack).
