Some Examples of Cracking

Windows Cracking

1).BIOS Password

Breaking

2).Windows Logon

Password Breaking

Bios password breaking

We can break BIOS password in any one of the following ways:

Trying default password

Hardware approach

Trying default passwords some default BIOS passwords

Lkwpeter AMI cmos

j262 Award AMI!SW1

AWARD_SW bios AMI? SW1

AWARD_PW BIOS password

Biostar setup hewittrand

„j262‟ opens most version of Award bios; it works about 80 per

cent of the time

Hardware approach

If the default passwords did not work, then try to reset the Bios to its default settings so that it asks for no password at all. Procedure for hardware approach is as follows

First, we have to open the computer and then look for a round lithium battery, it probably looks like a silver coin. So, remove the battery and after 30 seconds or so put it back.

Window log on password

breaking

To hack windows login password, reboot and wait for the message:

When we see the boot menu on the screen, press F2 or F12 before “Starting

Windows 9x…” . The boot menu will come up. Select option to boot into DOS

.

C:\>cd windows

C:\windows>ren *.pwl *.xyz // RENAME

Or delete them by typing

C:\windows>del *.pwl *.xyz //DELETE

Easy and Simple approachOn many computers a series of

keystrokes may crash the password program.

keep pressing ESC 15 to 20 times . This will result in the crashing of the password program and the computer will continue booting .

BY BOOTING

We can break into a computer by using live tools like conboot live cd which are readly available on internet .The live cd can be used to make a bootable pen drive and then we can break into any computer.
