I remember that I could set a password for my computer with a single command in the runtime? How?

It can be set from the control panel, and the specific steps are as follows:

Control Panel - User Accounts - Change Account Create a new account - Create a password is you.

Of course, if you are afraid of forgetting, you can also set the password prompt.

Or the best way to do it.

There are two places to set passwords in CMOS. One is the premium user password and the other is the general user password.

The computer will ask for a password when it starts, and one of the passwords can be started on the computer; If you want to enter the CMOS settings, you will need an advanced user password.

The computer considers the CMOS settings to be highly confidential to prevent others from changing them, and the authority of the advanced password is higher than the user's password on the CMOS setting.

To put it simply, if both passwords are set, then you can use the advanced password to enter the working state, and you can also enter the CMOS settings, while the user password can only enter the work, and you can also enter the CMOS to modify the user's own password, but other than that, you can not make other settings on the CMOS. If you only set a password, whoever you have has both permissions.

Move the cursor to the password setting, press Enter, enter the password, press Enter, the computer prompts you to re-enter the password to confirm, enter and then press Enter; If you want to cancel the password you have set, you can press enter directly when prompted to enter the password, and the computer prompts you to cancel the password, please press any key, and the password will be canceled after pressing the key.

Take special care to remember once you have set your password. If you set a boot password for your computer, and then forget to play it with your hips, your gown, your heart

If you really forget the password, you can't start the computer, for the master, disassemble the computer host and then carry out CMOS discharge, you can let the computer forget the password, but this needs to find someone who is very familiar with the computer hardware and refer to the motherboard manual to do it, and CMOS forgets all the set values at the same time, and must be reset to all settings. It's best to keep your password in mind!

The advanced password is the content of the Supervison password in CMOS.

The general user password is the user password

1. Restart the computer, press the F8 key immediately after the boot screen appears, and select "Safe Mode with Command Line".

2. At the end of the running process, the system lists the selection menus of the system superuser "administrator" and the local user "zhangbq", and clicks "administrator" to enter the command line mode.

3. Type the command: "net user zhangbq 123456 add" to force the password of the "zhangbq" user to be changed to "123456". If you want to add a new user here (e.g

If the user name is abcdef and the password is 123456), type "net user abcdef 123456 add", and then you can run the "net localgroup administrators abcdef add" command to promote the user to the administrators group and give the user super permissions.

4. Restart the computer, select Normal Mode to run, and you can log in to the "zhangbq" user with the changed password "123456".

1. Restart the computer, press the F8 key immediately after the boot screen appears, and select "Safe Mode with Command Line".

2. At the end of the running process, the system lists the selection menus of the system superuser "administrator" and the local user "zhangbq", and clicks "administrator" to enter the command line mode.

3. Type the command: "net user zhangbq 123456 add" to force the password of the "zhangbq" user to be changed to "123456". If you want to add a new user here (e.g

If the user name is abcdef and the password is 123456), type "net user abcdef 123456 add", and then you can run the "net localgroup administrators abcdef add" command to promote the user to the administrators group and give the user super permissions.

4. Restart the computer, select Normal Mode to run, and you can log in to the "zhangbq" user with the changed password "123456".

Use "administrator".

We know that in the process of installing Windows XP, the first thing is to log in with "Administrator" by default, and then we will ask to create a new account, so that we can log in with this new account when entering Windows XP, and only the created user account will appear in the login interface of Windows XP, and "Administrator" will not appear, but in fact, the "Administrator" account still exists. And the password is empty.

When we understand this, if you forget the login password, on the login interface, hold down the CTRL+ALT key, and then press and hold the del key twice, the classic login screen can appear, at this time, type "administrator" in the user name, the password is empty to enter, and then modify the password of "zhangbp".

Recover your password at the command prompt.
