Method1. Use Windows Vista installation disk
Insert Window Vista installation disk to the CD-ROM drive, restart your computer. Do the settings under CMOS to boot the computer through CD. When the installation interface appears, click "Repair Your Computer" (repair system) in the subsequent pop-up dialog box, select the "Command Prompt". After the system calls the command prompt window, enter "mmc.exe" and press “Enter”, then the console will be called. Select the file "Add / Remove Administrative Unit", the system will pop up another dialog window once again. In the left side of the dialog window select "Local Users and Groups", and then click "Add". At this point, the system will add "Local Users and Groups" to "Console Node". Click "OK" to complete the adding process. After adding is completed, the system returns to the console interface, click "Local Users and Groups" on the left side of the window, then click "User” and the system will list all the users in the right side of the current window. Right-click the user you are to crack, select "Set Password" in the pop-up "Set Password for Users" dialog box, and click "Continue”. The system pops up a window for you to set a new password. At this point, the Vista system does not require you to enter the previous password, but to set a new password directly. After you enter a new password, click “OK”, and the system will pop up a dialog box, indicating the setting is successful.
Method2. Use software programs to recover the password
Well, I’m a computer fun and very interested in computer. Then the above methods are very suitable for me, after several settings will do the job. However, there are still some friends who are not familiar with computer settings. What I said above just doesn’t make sense to them, does it? Well these friends are recommended to use computer software tools. Then you don’t have to touch those annoying terms but to follow the instructions with mouse clicking and pressing keys will be OK. Windows Password Unlocker 4.0 is highly recommended as they are just of this kind. They can automatically clear the administrator password and easy to operate.
