How to set the power-on password to the computer?

Enthusiastic netizens: For Windows XP, there are generally three ways to set up the power-on password, that is, the system user password, the system startup password and the BIOS password. The methods are set as follows:

First, the system to set the user password method: Start → control Panel → user account → Select your account → create a password → enter two password → press the "Create password" button can be. If you want to cancel the password, simply enter when you require a new password in step 2nd.

Second, the system to set the starting password method: In addition to being able to set the user password in the Control Panel's user account to ensure system security, Windows XP provides a more secure and effective "system startup Password", which is displayed prior to "User password" on power-on and can also generate a key disk. If you set the system startup password, the system will be more secure. Windows XP Sets the system startup password in the following ways: Click Start to Run, enter "Syskey" in the Run dialog box (don't enter quotes), press OK or enter, eject the "secure Windows XP Account Database Security" dialog box, and click "Update" in the dialog box. button, eject the "Start Password" dialog box, select the "Password Startup" single option, enter the password at the start of the system below, press the "OK" button.

To cancel the "Start password" of this system, press the above action in the "Startup Password" dialog box, select the "System generated password", and then select the following "Save startup password on this computer" can be determined after the startup password will be saved to the hard disk, the next time the startup will not appear when the password window. "Startup Password" appears before the login screen, only if you enter the correct startup password, will display the login screen, users can enter the user name and login password fully logged into the system. As such, the system has two password protections.

Three, the BIOS set the password method (different machine):

1, Boot press the DEL key into the CMOS settings, move the cursor to the "Advanced BIOS Features (Advanced BIOS feature Settings)" Enter, open the "Advanced BIOS Features" page, find "Security Option" ( Check password mode) or Password check (check password) to set it to system (Note: This item has two set values system and setup, set to system when the power-on into CMOS settings and enter the operating system to enter the password; Set to Setup when the only power-on into the CMOS settings to enter the password), press Esc key back to the main page;

2, in the main page to move the cursor to the "Set Supervisor Password (Super Administrator password)" Return, in the window appears to enter the password and return, in the window appears again enter the same password and return, CMOS will be back to record the password and return to the main page.

3, on the main page to move the cursor to the "Save & Exit (Storage exit)" Return, press the Y key, and then enter. In step 2nd, select "Set User Password" To set user password, the difference between user password and super Administrator password is: The user password to enter the CMOS settings can only see can not modify. The security of the system-initiated password is the highest in the above three types of passwords, followed by the user password, the minimum security of the BIOS password. The BIOS password can be removed by removing the battery on the motherboard, and the user password can be found on the internet a lot of cracked methods, but the startup password is also difficult to find a way to crack. It is recommended to set the startup password and user password at the same time, so that there is a double password protection, not only to enter the password on the power-on, but also in the temporary departure by the Windows logo key (CTRL and ALT between the key) and the letter L key lock the computer (when locked, the computer returns to You must enter a user password to return to the system for normal operation) so that others cannot use
