If you do not have the current passwords, it's going to be a bit of a problem. The BIOS password mostly. Contact Dell Support: http://www.dell.com/us/business/p/optiplex-390/pd Perhaps they will give you a one-time BIOS password. If it's a login password, you could try a Full Factory Recovery. If someone put the passwords in , I would ask them, that's the easiest way.

Best is to reset the administrator password using the Offline NT Password & Registry editor.
You can download it at the following link: http://pogostick.net/~pnh/ntpasswd/

This utility will enable you to reset the password of any user that has a valid (local) account on your Windows NT/2k/XP/Vista etc system.
The link above includes some directions on how to use this utility. But the basic idea is to download the ISO image & burn it to a CD. Then use this CD to boot up your laptop & reset the administrator password

Go into windows as administrator and reset your password. If you don't have the administrator password, take it to an authorized repairer. If you mean the hdd password, and you haven't got the password, purchase a new hdd and set up a new system. The old hdd is not usable.

How do i get samsung all in one off of demo mode i bought a floor model and it only runs in demo mode there is also an administrator account already on it is there a standard password for that?


You should get it from the sales person who sold it. Otherwise you can clear the administrator password with tools available on the web. You may be safer using a system restore disk to return the computer to factory default settings.

I forgot my password for my dell optiplex 740?


I think you are running on Windows vista or 7, in this case you have to remember the Administrative password. Reboot your PC and before Windows logo arrive press F8 couple of times, a list of option will arive, choose "Safe Mode" you should be able to login with an Administrative account. From there go to ccontrol panel> accounts .. delete the account and add a new one.

In case if you forgot the Administrative password you have to hack into the system and delete the account:

Reset log on password



If a user account needs to be reset, logon as the administrator or as a user with administrative access, and then follow these steps:


Click Start, point to Programs, click Control Panel, double-click Administrative Tools, and then double-click Computer Management.


Expand the Local Users And Groups object under System Tools, and then click the Users folder.


In the right pane, right-click the appropriate user object, and then click Set Password.

Type the appropriate password, and then click OK.


Click OK to acknowledge that the password change succeeded.

Close the Computer Management console and Administrative Tools windows.


The user can log on with the new password.


To Reset the Administrator's Password

Log on to the computer as a user with administrative privileges, and perform the steps


listed above for the Administrator account.

If the Administrator password needs to be reset, and there are no other users with administrative access, there is no way to recover the password and the operating system will need to be reinstalled.


or if you have not set a bios password

restart your computer you will see on your screen to press a certain key to enter bios usually the Delete or the F2 key
press and hold that key to enter set up BIOS where you can set or remove your password

this will differ depending on you computer and bios

hope this helps
