The steps that you should follow will vary, depending on whether your computer is on a domain or a workgroup. To find out, see "To check if your computer is on a workgroup or domain" in What is the difference between a domain, a workgroup, and a homegroup?
Because your computer is on a domain, only your network administrator can reset your domain password. To reset a password for a local user account (an account that provides access to the computer, but not to the domain), follow the steps below.
On the Users tab, under Users for this computer, click the user account name, and then click Reset Password.
Type the new password, confirm the new password, and then click OK.
If you forget your password, you can reset it using a password reset disk for your user account (or the password reset information stored on a USB flash drive). If you don't have a password reset disk, you'll need to get someone with an administrator account on the computer to reset your password for you.
If an administrator resets your password, you might lose access to some of your files. For more information, see What are the risks of resetting a password?
If you enter the wrong password when you attempt to log on, Windows displays a message that the password is incorrect. Click OK to close the message.
Click Reset password, and then insert your password reset disk or USB flash drive.
Follow the steps in the Password Reset wizard to create a new password.
Log on with the new password. If you forget your password again, you can use the same password reset disk. You don't need to make a new one.
