Break Administrator Password In XP

Password cracking is the process of recovering passwords from data that
has been stored in or transmitted by a computer system. A common
approach is to repeatedly try guesses for the password. The purpose of
password cracking might be to help a user recover a forgotten password
(though installing an entirely new password is less of a security risk, but
involves system administration privileges), to gain unauthorized access to a
system, or as a preventive measure by system administrators to check for
easily crack able passwords.

After windows accounts appear  , right click on account you want
to break password and choose type of attack , in this example I chose brute
force attack. Brute force actually means to start with a letter a and
encrypting it. Then see if the encrypted strings match. If not then b, c,.. until
we‘ve gotten to admin. Then the encrypted strings will match and we‘ll
know that is the right password. Brute force attack is the slowest method of
cracking, but there is no risk that you‘ll not find the password. The thing
about brute force is that the time of cracking rises rapidly depending on how
long the password is, how many characters are being used in it and so forth.
