Changing ANY user password without having to know the existing password

Changing ANY user password without having to know the existing password

It enables the user to re-password any account without having to know the existing password and also shows you every account that exists on the machine (even the ones that are hidden). This is a good tool to use if you forgot a password to say your administrator account and you needed to be logged into the admin account for any reason.

To view all of the user accounts:

1) While logged onto the computer, click on Start>Run>and type in CMD.

2) From the command prompt window, type in net users. This will show you every account that is made onto the computer whether it is hidden or not.

-----------------------------------------------------------------

To change an account password:

1) While logged onto the computer to an account that has administrative rights, click on Start>Run>and type in CMD.

2) Type in net user then the name of the account then * and press enter. heres an example: net user administrator * or net user "Joe Smith" * . Put the name in quotes if it contains spaces.

3) From there it should ask for a new password. Type in your new password (type very carefully - the command window won't display what you type) and once more to confirm it. If you get the message that the command succeeded successfully you're all set!!

    Worked for me. Had to F8 safe mode with command prompt first. Worked like magic. Id just disabled all accounts for faster start up and it decided that it now needed a password and locked me out. I was totally bolloxed. Then I read this. Nice one !

    The tip from the author of this article, doesen't work if you don't use a account with admin-rights, if you try you will only get a systemerror 5. Mai wrote: "It only work under some condition. How do you all invisible user ( hidden ) to be visible.? I had few other user nam, but I can not change pass word by enter your command "net users *" Restart, hit F8 after BIOS-check and select safe mode from the list, then they will be visible from the controlpanel under user accounts. Unknow user wrote: "what if u do not have admin access and need to change admin pw because your dumbass boss lost the pw and u need full access to windows I can start in safe mode and get command prompt however if need admin access i am screwed right?" Interesting, it may work, but doesen't think so..give it a try ;) You could also try with the same command with the recovery console (insert the win. disc, restart, let the menus load and hit R for recovery console). Have fun if it works ;)

    This tip works wonderfully. I needed a "go around" for a jobsite that had changed and forgotten the default "admin" password we leave on the system. I tested it by adding a second admin account to my personal machine - then set it's account level to "Limited" - logged on with the account to see if I can change the password - worked BOTH times, Limited and Admin!

    I was in a tight spot with a machine which had a complex configuration and the admin password had become corrupt (major disk problems). These instructions have saved me a huge amount of time - which i don't really have. I was able to login, get the machine running and grab an image before it died completely. A BIG thank you to all concerned. Regards, Richard IT&T Support City of Ryde Council Sydney, Australia

    Works on some system and sometimes does not work on other systems with same OS and SP. I guess there's more to this technique other than just typing those commands.

    Soo dumb. You need admin rights for that. To do it without admin rights you need to run a batch job that will generate command prompt as a logon.scr. Then use that code. For that to work as well, you need your system type to be FATFAT32. It wont work on NTFS. If ur interested in password exploitation, then tryout brute force codes and keyloggers. Remote passwords are another story.

    I have a limit user password but I want to find Admin password. If possible I want to get a master password for admin users, so that I will logon to any Admin user without having its password. e-mail: hamid_baraywal@yahoo.com
