Some friends don't want others to use their computers casually and want to set the power-on password. How to set it? There are generally three ways to set the power-on password, namely, system user password, system startup password and BIOS password. The setting methods are as follows:

1. System user password

Open the control panel, double-click "User Account", as shown in Figure 1, select an account, click "Create Password" in Figure 2, set the password in the corresponding position in Figure 3, and press the "Create Password" button.

if you want to cancel the password, just press enter when you ask for a new password in figure 3.

second, the method of setting the system startup password

in addition to setting the account password in the user account of the control panel, Windows XP also provides a more secure and effective "system startup password", which is displayed before the "user password" when booting. Set the "system startup password", and the system will be more secure. Windows XP can set the system startup password as follows:

Click the Start button, enter "Syskey" in the Run dialog box, as shown in Figure 4, and press OK or press Enter. The dialog box "Ensure the security of Windows XP account database" pops up, as shown in Figure 5. Click the "Update" button in the dialog box to pop up the "Startup Password" dialog box, as shown in Figure 6. Select the "Password Startup" option, enter the password at system startup below, and press the "OK" button.

to cancel the startup password of this system, in the startup password dialog box in figure 6, select the password generated by the system, and then select the "Save startup password on this machine" below, click OK, enter the password again in the pop-up box, and the startup password will be saved on the hard disk, and the startup password window will not appear next time.

the "startup password" appears before the login screen. Only after entering the correct startup password can the user enter the user name and login password to log in to the system completely, so that the system is protected by double passwords.

third, how to set the password in the BIOS

press the Del key to enter the CMOS setting, find "Advanced BIOS Features" and press enter, find "Security Option" or "Password Check" and set it to "System". This item has two set values, System and Setup. When it is set to System, you must enter a password when booting into CMOS settings and entering the operating system. When it is set to Setup, only boot into CMOS settings. To enter the password, press Esc to return to the main page.

find "Set Supervisor Password" and press enter. Enter the password in the window that appears and press enter. Enter the same password again in the next window and press enter to confirm. CMOS will record the password and return to the main page.

find "Set User Password" to set the user password.

the difference between the user password and the super administrator password is that you can only view and not modify the CMOS settings with the user password.

find "save &; Exit "Enter, press the Y key, and then enter to save the settings.

among the above three methods, the system startup password is the most secure, followed by the user password, and the BIOS password is the least secure. The BIOS password can be removed by removing the battery on the motherboard; Many ways to crack user passwords can also be found on the Internet. But it is still difficult to find a way to crack the startup password.

it is recommended to set the startup password and user password at the same time, so that there is double password protection. Not only do you have to enter the password when you start the computer, but you can lock the computer by pressing the Windows logo key (the key between Ctrl and Alt) and the letter L key at the same time when you leave temporarily (when you lock it, the computer will return to the login screen, and you must enter the support password to return to the system for normal operation), so that others can't use your computer.

How to set the power-on password

Setting the power-on password, setting the screen saver password and setting the file password are all beneficial protection measures, but you can't rely too much on the effectiveness of the password, because these passwords are easy to crack for professionals. But for the general office environment, setting the power-on password still has a considerable effect. Let's take a look at how to set the boot password in BIOS.

press the Delete key of the keyboard after booting to enter the BIOS interface.

there are several ways to set the password, and there are many solutions

1.CMOS password, which I won't say much about

There are two kinds of passwords, one is the boot password, and the other is the password to enter the CMOS management

Clearing method: 1. Software

2. debug command in the system

-o 7 16

-o 71 16

(for Award) P> 3. Open the case, CMOS discharge

2. System password

This is more complicated, because there are still problems of multiple systems

Here, it is only said that the password of a single system

win9x is stored in the pwl file. But when we enter Win9x, the user can just click Cancel and solve it by modifying the registry: open HKEY _ local _ machine \ system. Current control set \ control \ shutdown sub-item, create a new "string value" in the right window, named "FastReboot", and set the "numerical data" to at the same time.

win2, like winxp, supports NTFS-formatted hard disk partition, which has high permission configuration. Of course, this system also has many restrictions on user rights. The administrators group is level 1 (the highest authority among ordinary users), such as the default administrator setting a password, and deleting or prohibiting the use of other accounts.

Of course, there are solutions when you forget the password

The user passwords of these two systems are stored in %system%\system32\ There is no extension in the config\sam file. For most versions, it is enough to delete this file under DOS, but DOS only knows the hard disk partition in FAT and FAT32 format. We can use software to identify the partition format of NTFS, such as NTFSPro

3. Use third-party software to set the password of the folder

4. Use third-party software to set the password of the file

how to set a password for a computer

password setting method

although there are multiple BIOS versions, the password setting method is basically the same. Take the version of Award 4.51 PG (as shown below) as an example. In the process of computer startup, when the prompt "Press DEL to enter SETUP" appears at the bottom of the screen, press and hold the Del key to enter.

the method is: when the prompt "Press DEL to enter SETUP" appears at the bottom of the screen, press and hold the Del. The items related to password setting are:

"BIOS features setup"

"supervisor password"

"user password"

Select one of them. Select the administrator or user password item and press enter. Enter the password, and then press enter. You will be prompted to check the password, enter the same password again and press enter. It should be noted that after making any settings, you must save them when you exit to make the settings take effect. (The saving method is: after setting, select "Save &; "EXIT SETUP" or press F1, the prompt "SAVE to CMOS and EXIT(Y/N)" appears. At this time, press the "Y key" to finish saving. )

there are several specific settings:

setting method 1: set either SUPERVISOR PASSWORD or USER PASSWORD separately, then open BIOS FEATURES SETUP and set the Security Option to Setup, then save and exit. In this way, when you press the Del key to enter the BIOS setup screen, you will be required to enter the password, but you will not be required to enter the password when you enter the operating system.

setting method 2: set either "SUPERVISOR PASSWORD" or "USER PASSWORD" separately, then open "BIOS FEATURES SETUP" and set "Security Option" to "System", save and exit. In this way, not only the password is required when entering the BIOS settings, but also the password is required when entering the operating system.

setting method 3: set "SUPERVISOR PASSWORD" and "USER PASSWORD" respectively and adopt two different passwords. Open "BIOS FEATURES SETUP" again and set "Security Option" to "System" to exit saving. In this way, password is required for entering BIOS setup and operating system, and any password can be entered into BIOS setup and operating system. However, there is a difference between "administrator password" and "user password": when you enter the BIOS program with "administrator password", you can make any settings, including modifying the user password. However, when you enter with "user password", you can't make any other settings except modifying or removing "user password", and you can't modify the administrator password. Thus, in this setting state, the authority of "User Password" is lower than that of "Administrator Password".
