26. Some Examples of Cracking
Windows Cracking
1).BIOS Password
Breaking
2).Windows Logon
Password Breaking

27. Bios password breaking
We can break BIOS password in any one of the following ways:
Trying default password
Hardware approach

28. 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

29. 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.

30. 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

31. Easy and Simple approach
On 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.
