Recover your Windows Password



Ok some people keep on asking me the same thing, So ill put it up here. Incase you forgot your windows user account password OR if you have multiple user accounts and one of them is password protected, you can always crack the password.This trick wont decrypt the password, but instead you can set a new password and replace the old one. OK the trick here is you need access to command prompt.

Assuming administrator account is 'not' pass-worded 

  • You log on to a windows computer and it asks for a password. Now shut it down, Reboot.
  • Keep pressing F8 while the computer boots up.
  • Now choose to start windows in safe mode.
  • Now wait till safe mode boots up to user selection.
  • It will show Administrator account and other accounts present on the system.
  • Now if you are lucky log onto computer through administrator account.
  • Now you have access to command prompt. (Start>Run>Cmd).
  • Type net user <space> <user_name> <space> <asterisk>
  • (example: net user crimson *)
  • Then it would ask you for password, Type in the password (it wont display).
  • It will ask password for confirmation, Now enter it again and press enter.
Example: If my account name was Crimson.
I would type:
net user Crimson *
when asked for password: newpass
confirm password: newpass
now my old password would get replaced by "newpass"
now i can log onto my windows account with this "newpass"

Other Method
A bit advanced method using linux. You can log into linux if you have it installed on your PC, Or you can actually carry your linux operating system on a USB Drive. You can find more information about it on the internet. Google it. The steps which i will provide are supposed to be followed "after" you are logged into linux.
Using linux what you have to do is: 
Go inside "system32" folder in "windows", then there are these two files for the trick: "sethc.exe" and "cmd.exe"
Function of SETHC: press shift more than 5 times consecutively and it will show u a dialog box called sticky keys. Here pressing shift key initialized sticky keys, so we can initialize command prompt if we replace sethc file with cmd file. so using this trick, You can open command prompt on the welcome screen itself by pressing shift keys more than 5 times in a row.

Steps (while in linux):

  • Copy cmd.exe from Windows/System32 to Desktop
  • Rename this cmd.exe to sethc.exe
  • Copy this sethc.exe(fake) from desktop
  • Paste sethc.exe(fake) in Windows/System32
  • Now this replaced original sethc with fake sethc (which is cmd.exe).
so now when u press shift more than 5 times, it initializes sethc but sethc is actually cmd. now u have access to cmd on welcome screen so there itself you can change the password :D
