How Do I Retrieve System Password For Dell N4030

I am from Dell Social Media and Community.

If you have windows XP follow the steps below:

Boot using Windows XP Setup CD and follow the instruction like Accepting EULA, etc.
When it asks to repair your existing Windows installation, accept it and press "R" to run the repair.
Setup will start repairing your Windows and will start copying files, etc.
After a few minutes setup will restart your system and when it restarts don't press any key when it shows "Press any key to continue..." otherwise Setup will start from the beginning. Don't press any key and setup will resume where it left.
Now it'll start doing other tasks and will show a small progressbar with a few details in left side.
Look carefully at the details and when it shows "Installing devices", press <Shift>+F10 keys in your keyboard.
It'll open a Command Prompt window. Now type nusrmgr.cpl and press <Enter>.
It'll open the same "User Accounts" window which you see in Control Panel.
Now you can remove or reset any account password without any problem.

In windows vista we do not have such option and you will need to reinstall Vista.

For windows 7, follow the steps below:

Boot off the Windows disk and select the “Repair your computer” option from the lower left-hand corner.
Follow through until you get to the option to open the Command Prompt, which you’ll want to select.
First you’ll want to type in the following command to backup the original sticky keys file:

copy c:\windows\system32\sethc.exe c:\

Then you’ll copy the command prompt executable (cmd.exe) over top of the sticky keys executable:

copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exeNow you can reboot the PC.

Resetting the Password
Once you get to the login screen, hit the Shift key 5 times, and you’ll see an administrator mode command prompt.Now to reset the password—just type the following command, replacing the username and password with the combination you want:

net user "User name" MyNewPassword

Now you can login.

Let me know if you need any further support. I will be glad to help you.
