losing password on winxp

My computer was locked by someone. When l entered on winxp, my pc asked me the password of winxp,but I did not know what it was. I have used password which is administrator. But it did not work.I hope that you can help me to enter windows xp.

 

Reboot the computer.

 

If you have the administrator password, reboot into safe mode, open the administrator account, go to Users and change the password of the account you use to something that you know and start back into normal mode and use it from there.

If you are leaving the computer running with your account open for anyone to use, you are open to this abuse because anyone can set a password for the user's acount when it is open.

Set a password for your account and lock the screen when you leave. That way someone else will need to have an account to use or use the guest account if it is available. Password enabled screen saver can do this if you are sure that no one will go to the computer before it activates the screen saver. Windows key + L will lock the screen.

 

I know i sure found that out that windows xp will lock anyone even
out of the guest account If they don't stay with It.If you do not know the
administrator password your beat cause you cannot even get Into safemode without It?

 

You cannot find out what the password originally was, but you can replace it with your own as to gain access to your computer. You can use third party tools to do so, such as the "Offline NT Password & Registry Editor" linux bootable floppy found here:

Sorry, don't agree there. Locking the computer is not good practice unless you ensure you close all apps before doing it . Otherwise when someone comes along and uses the admin account to log you off, that nice Word document you worked on for hours and didn't save may well be lost. Much better - and more secure - to logoff when leaving.

As for the other poster who seems to think another user can reset your password if you leave your account logged in. Sorry, to change a password of a logged in user, you need to know the present password.

 

I guess there is not much you can do about a malicious administrator.

Leaving open documents would be a bad idea if the computer shuts down for any other reason, anyway.

I consider that locking the screen is a good idea if you are going to be away for a short time. Of course, it does not take much time to log off either.

Then again, so many don't do anything to make the computers secure in the first place. There is probably not much advice that can be given to improve this behavior.
