Log in and right-click My Computer-Administration-User to find your user name and right-click to change your password. If you cannot log in, please use the following methods.

2. If 2.administrator can't log in, he can only clear the password. Go to the computer store to buy a system disk with PE, then put it into the computer and start it with a CD (if you don't enter the CD interface, press F 1 1 or F 12 to restart it, and if you choose DVD, you can start it with a CD).

Method (1) to restart the computer. When starting the system login interface, hold down the Ctrl+Alt key at the same time, and then double-click the Del key, and a new login interface will appear. Enter the Administrator password in the user name, and then log in. After logging in, open the control panel and select/User Account/Change Account/Click the original "Account Name"/Change My Password/Enter a new password, and then enter the new password again.

If the computer administrator forgets the password, please use the second method or the third and fourth methods. Method (2) 1. Restart the computer, hold down F8 key until the advanced options screen appears, then release your hand, select "Safe Mode of Command Prompt" and press Enter.

2. At the end of the running process, the system lists the selection menus of system super user "Administrator" and local user "* * * * *", and click "Administrator" to enter the command line mode. 3. Type the command: "user * * * 123456/add" to change the password of "* * * *" user to "123456".

If you want to add a new user here (for example, user name is abcdef and password is 123456), please type "user abcdef 123456 /add". After adding, you can use the "local group administrator ABCDEF/Add" command to promote the user to the "administrator" of the system management group, and give him super privileges. 4. Restart the computer and select the normal mode to run. You can log in the user "* * * *" with the changed password "123456".

Methods (3) Using Windows xp system to install the CD-ROM repair system and crack the password of the super computer administrator. Step 1: Set the system to CD startup and put it into the system installation CD.

At this point, a warning window will pop up. After changing the password, some information in the system will be inaccessible.

This mainly refers to the files encrypted by EFS, and the certificate has not been exported before, so you will not be able to access these files after changing the password. If there is no such file, I don't care about it, just click Continue, then enter a new password and click OK.

Then close the local users and groups and the command prompt window to continue the repair installation. After installation, the system administrator account is "activated" again.
