There are various options and utilities that can make it possible to gain access to a computer with a lost password. Below is a listing of the most popular options and utilities available to try.
Log into an alternate account
Often many users will leave the administrator account alone or have other accounts with administrator rights. If you are not logging into the computer using the administrator account or have other accounts that you can utilize, follow the steps below to reset your other account's password.
- Reboot the computer into Safe Mode.

If prompted for a password, try pressing Enter on the keyboard for no password. If this does not work, try other passwords you may have used. If you are unable to log into the Administrator account, skip to the next suggestion.
- Once you have logged into the Administrator account, open the Control Panel and User Accounts.
- In User Accounts, select the account you want to change, click Change Password, and then enter the new password or click remove the password to remove the password from the account.
