Revive the forgotten Windows XP password

Recently has a colleague's computer forgot the password, the system is the Windows XP, what method solves? Thank you.

Edit answer: You can try the following methods:

Method 1: Use the "Administrator" (this method applies to situations where the administrator username is not an "administrator")

We know that during the installation of Windows XP, we first log in as "Administrator," and then ask to create a new account to log in with this new account when you enter Windows XP, and in Windows XP login interface will only be created this user account, no "administrator", but in fact the "administrator" account still exists, and the password is empty.

When we understand this, if you forget the login password, in the login interface, hold down the Ctrl+alt key, and then hold down the DEL key two times, you can appear classic login screen, at this time in the user name type "Administrator", the password for empty entry, and then modify the "ZHANGBP "Password.

Method 2: Press (F8) and select (safe Mode with Command when the computer is started Prompt)

After the election (administrator) will jump out of the window (command prompt);

Add a user with the (net) command, for example: Add a user name to alanhkg888, and the command syntax is as follows:

NET user Alanhkg888/add

To elevate the new user to the Administrator's power, for example: to elevate the power of the user alanhkg888 just now, the command syntax is as follows:

net localgroup Administrators Alanhkg888/add

Complete the above steps to restart the computer, in the Start screen will add a user alanhkg888, select the alanhkg888 into;

After logging in (console)→(user account)→ Select users forget password, then select (uninstall password) after (log out);

In the login screen to select the original user can be no need for password conditions inferior into (because has been uninstalled);

Delete the newly created user, select (alanhkg888) in the console)→(consumer account)→, and then select (Uninstall account);

* Not applicable to the password that you set (administrator) when you forget to install

Also does not apply to NTFS partitions, which may be security-enhancing.

Method Three: If it is the administrator password forgotten, you can consider the following method.

The first trick to forget about the Administrator password: delete sam files

For SP3 previous workgroup mode Windows2000, after deleting the sam file (no suffix) under the Winntsystem32config folder, all users of the machine were lost, logged in with the administrator, and the password was empty.
