How to Crack Windows Administrator Passwords

Some times it necessary to know admin passwords in schools ,collages to log in with admin privileges to do various things

There are many way to crack passwords. But in this tutorial I will explain a very basic method using a single tool to crack windows password . This might come handy in places like schools ,collages where you cant use your live Linux cds , usb ..etc because your being watched

Things we need :

1. Pwdump or Fgdump to extract password hashes

In this tutorial I will be using Pwdump

Extracting Password hashes :-

1. Open My computer and go to C:\Windows\system32 . now place the Pwdump file which we download earlier

2. Now open command prompt and navigate to C:\Windows\system32 \Pwdump

Using cd command and click enter

Example :-

Cd C:\Windows\system32 \Pwdump

3. Now you can see a list of Pwdump commands as shown

4. Now enter pwdump - localhost >>“ destination of output file “ (for 32 computers) and pwdump -x localhost >> “destination out put file “(for 64 bit computers )

Example :-

Cd C:\Windows\system32 \Pwdump localhost >> C:\hashes.txt

Cd C:\Windows\system32 \Pwdump -x localhost >> C:\hashes.txt

5. Now open  the Out put  file  you can see the names of the different  users with password hashes Now copy the hashes  corresponding to the admin account

Cracking The Hashes

Considering that we are in school/collage were we cant use tools to crack passwords so as an alternative we are using online password cracking sites

1. Go to online password cracking sites like www.cracker.offensive-security.com , www.onlinehashcrack.com and paste the hash select hash type as LM and click decode

2.By this way we are able to crack windows password using a single tool

Note:- If your not able to crack password hashes online use tools like john the ripper to crack password hashes . You can even copy the hashes and decoded it in your house
