How to bypass Windows XP login passwords from scratch

Step 5: The guest account method

If nothing so far has worked, but there is a non-passworded guest account, you may have hope yet.
Go into the guest account, click the start menu, click run, and then type in "cmd". A black window should pop up.
Then, after typing "net user administrator *" , press enter and you will be given directions to create a new password for the administrator. After typing in the new password, press enter and close the window. Log off, then get into the administrator account with the new password.

on my guest account it when i execute the net user administrator * command and type in the password and confirm it, it says:
system error 5 has occured.

access is denied.

any way around this??

It is called ophcrack. Google it. Learn what it is. Download it. Write the disc image to a disc. Boot off it.

ophcrack is not exactly fast or covert and (hypothetically speaking of course) if a teacher sees it on your screen they will no doubt take a closer look, after that the shows over.

I would never be stupid enough to run my own operating system on a school computer, they would probably arrest me, who knows. I meant more for a home computer where you only have user rights and you parents aren't home.

thats what happened to me too, i think its because the guest account is not an admin

if you cannot run command prompt on limited users or guest accounts just open notepad, and type in start. save it as cmd.bat and open it and it should open up command prompt. if it isn't that being the problem, then it is most likely the ophcrack thing they described above.

ophcrack, is a linix based program that boots from a CD and it will reveal the passwords for all users on the offending windows computer and usually it will do it under five mins, but why not just pop in a DVD version of Ubuntu and use it instead of screwing around all day with windows ...... To use OPhcrack goto sourceforge, download it, burn the ISO to a CD, put it in the computer you want to access, restart the computer, when its starting up hit the DEL key (( some models it's F12 or F10 )) to access the BOIS, if you find it's password protected simply remove the small lithium battery from the computer or short out the password reset pins, some even have a reset button right on the mother board, select the boot from CD option and save your settings and exit. this will restart your computer and it will boot from the CD. Slax will start up and do the rest of the work for you, and with in a few mins you'll be showen all the users and there passwords, Remove the CD and hit the reset button on the front and just log onto there desktop and do what you want ..... And if you don't change there password chances are good they won't even know you where on there computer to start with especially if you set the Bois back to the way it was ... Once again like LinixH4x0r said WINDOWS SUCKS ..... (( and this doesn't work on linux setups .... Or on Vista using a TPM with Bitlocker or a system using PGP's Wholedisk Encryption, then you need to learn what's called a cold boot, but that is kinda beyond the scope of this instrucables ))

mine says something like its not valid......

[rabbitkillrun]

step 5 one doesn't work on limited accoutns... you always get access denied... i am currently writing an instructable on how to do this (that is how i came across this... doing my research to make sure there isn't already one...) so check it out when i'm done if you're still stuck...

most guest accounts do not have the access requirements to make changes using the command prompt If you really want to get in to windows - you can download an illegal windows password finder program
