Hello my son put an administrator password on my c540 i cannot unlock it

My son has put a password on his phone and has forgotten it. How do I unlock it?

you will need to either buy a unlock software or factory reset your computer windown and mac login screen is un passable to people who dont have very litarate skills on pc's

Sometimes the existing user is the Admin. This question arises every day, and here is my post. Good Luck


Lost Windows password:

• Login as Administrator. Try with no password (load safe mode if you don't see Administrator). Press F8 during boot to access Safe Mode.
  
• Login as other user (if other user is availible) and manage users. Must be an administrator.
  
• Reformat computer.
  
• Use 3rd party software to remove password. Like http://www.top-password.com/reset-windows-password.html
  

You will need your son's password to gain administrative rights to the computer, no other password on your account will be excepted, windows is designed to protect against unauthorized access attempt's

Resetting password: username and password) b> *Start your computer
*Keep pressing "F8" as the computer starts.
*This will enter the computer in Safe Mode.
*(When the window "Advanced Boot Options" opens, choose "SafeMode" with arrow key and confirm by pressing the Enter key, then computerenters Safe Mode.
*Once you are in the Safe mode Click "Administrator" on the Windowslogin screen.
*Take note that you have set the Administrator password before, you need toinput the changed password instead of leaving "Password" field blank.
*Then click Start > Control Panel > User Accounts > Select the accountthat is locked and change the password.
**Restart computer and login into the account you just created using your newpassword.

at Windows XP's Welcome Screen, simply press Ctrl-Alt-Del keys sequence together twice, and you will be shown a Log On to Windows menu where you can specify the User Name and Password. In the User Name text box, key in "Administrator" (without quotes) and leave the Password field blank. Then press Enter or click on OK. If there it is not a password protected Administrator account, or blank password is set, then you will be able to access the Windows with full administrative privileges as Administrator.

Then simply click start > control panel > User accounts then select your sons account and click edit then click remove password. once done simply log off and then log in to your sons account and no password will be asked for. If your son is the root administrator then you will need to get software to reset the password for you

If you have any other users you can try to remove your son's password from the other user account. If you don't then you'll need a password reset boot disk.

boot the system into safe mode (hit the F8 key while booting). Login as the Administrator account. Then go to control panel -> users and select your son's user saccount, and select to remove the password.

If that doesn't work, use the NT Offline Password and Registry Editor tool to reset the password:

What version of windows are you running?

Yes, when you switch the laptop on hold down the F8 key until you see a black screen with a list of white text, one of the options will be "Safe Mode", use the arrow keys to highlight safe mode (just safe mode, not safe mode with anything) and press return. The computer will start to the welcome screen and you will see a user-name you don't normally see called "Administrator". Click on Administrator and you will find it is not password protected (in spite of the fact that the Administrator account has more access to the system than any other account!) when the administrator profile loads it will ask you if you want to continue in safe mode and you do. click start, click control panel and click on users and groups now click on your son's user account and click remove password. now click back, click on the Administrator account and click change password, the old password should be left blank and you're new Administrator password should be something at least 7 letters, numbers and special characters (!@£$%^&*) long that you can remember. Now just restart and let it start up normally, once loaded advise your son to set a password he can remember or at least write down somewhere safe.
