My parents have set a password for my computer, how can I know

It seems that the password cannot be seen but can only be changed, which is the role of the software. You can create a new Windows from your computer and get a password yourself. But it's best to communicate more with your parents and ask them to turn on the computer for you.

Don't do this, you should find a way to get your parents to remove the password.

Without an impermeable wall, it is impossible not to be discovered.

Method 1:

If you have a Win PE disc at home (you can go to the bookstall and buy a computer fan, it comes with the CD) or the Ghost XP system, you can solve the problem by clearing the password in the installation CD.

Method 2: 1) Start the computer and use the DOS boot disk (e.g. Windows98 boot disk) to enter the pure DOS state.

2) At the DOS prompt, follow the steps below:

cd (switch to root).

cdWindows system32 (switch to system directory).

mkdirtemphack (create a temporary folder).

Backup backup deletion will be renamed.

exit

3) Restart the computer, wait quietly after the login waiting screen appears, if you do not modify the screen saver time, about 10 minutes, the system will automatically start the login screensaver program, but because it has been replaced, so the system will start and enter the command line prompt state.

4) At this point, we can use the command netuserpassword to change the password.

For example, if a super administrator account is admin and wants to reset his password to admin, you can use the command: netuseradminadminadmin to change the password after entering.

5) Next, do you want to go into the desktop system and see what is on the hard drive? Enter the explorer command in the command line prompt state to try, is it very smooth to enter the Windows desktop?

Back up and, replace all of the two steps, then restart, wait quietly, and instead of a command line prompt, the user manager appears, and then we have permission to add ourselves to the administrator group.

Method 3: Because WindowsXP in the installation process, first log in with the default administrator, many friends did not notice to set a password for it, but according to the requirements to create a personal account, after entering the system to log in with this account, and in the login interface of WindowsXP only appears this created user account, not Administrator, the actual account still exists, and the password is empty.

Knowing this principle, you can start it normally directly, after the login interface appears, press Ctrl+Alt, and then press del twice, the classic login screen will appear, at this time, fill in the administrator at the user name, and the password is blank to enter, and then, you can enter the "Control Panel" of "Users and Passwords", and change the password of the user you want to modify.

How to check your computer's current password:

To find out the password for your computer, it's easy to click on the Start menu and open Run.

Enter rundll32, usersrundll in the input box and press enter.

When opened, deselect the option "To use the machine, the user must enter a user name and password".

After canceling, click OK, and do not enter the account and password that you want the computer to automatically log in every time in the pop-up dialog box.

Once all the settings are set, select the option "To use the machine, the user must enter a username and password".

How to change your password:

After the computer is turned on, open the control panel interface.

In All Control Panel Items, find User Accounts and click on it.

In the interface, click Change Password to jump to the Change Password interface.

In the interface, you will be asked to enter the current password, if you do not remember the current password, you will not be able to enter the password change, and an error message will be displayed.

When you click on the Delete Password option, you will be taken to the password deletion window, but you will also be prompted to enter your current password.

However, if you don't remember the current password, press F8 when you turn on the computer, enter the safe mode with command prompt, and enter net user+username+new password add, you can forcibly change the password of the user name to a new password.

Since it's not a forgotten password to recover the password.

There's no other way but to ask the person who set the password.

This is the only way to use it normally.

Cracking the password Many ways are to empty the password and enter it, which is not what you want, or it is to enter the PE system.

It is best to install a dual system. Select your system to enter at boot time.

At present, there are more direct password changes, and there are very few direct passwords, because there are only a few ways to crack the password, and if your password settings are more complicated, you may not be able to crack it in 3 days, of course, commercial cracking software may be faster.

There is no other way than to wipe out the password with a CMOS discharge.

Or guess it, the password used by everyone in the family is the same.

(1) Start the computer and use the DOS boot disk (e.g. Windows98 boot disk) to enter the pure DOS state.

2) At the DOS prompt, follow the steps below:

Don't do bad things.

Call 10086 to tell him his ID card and let him check it for you.

You don't necessarily have to know the password, but I'm not a hacker, so I don't know. But you can "save the country by curve" and set up the VIP login mode, which can also be logged in without an account. Uh, sorry, it's guest mode.

Why don't you set up another account yourself, aren't you surfing the Internet now, just create a new account in a matter of minutes.

Do you want to know what password your home computer is? BIOS password? User password ?

BIOS password I only know that the discharge can eliminate the password But how to crack it I don't have that level.

The user password is very easy to get You open the Control Panel - Management Tools - Local Security Settings - Account Policy - Password Policy! Put the password retention period very short, and the expiration will prompt the password to expire, so that you can set up another keylogger software to open it first, and then let your family change the password amount. I'm not teaching people to learn bad...

ophcrack software, specialized in cracking windows login passwords, this needs to be used with the rainbow table, the larger the rainbow table, the greater the possibility of cracking it.

The time complexity is related to the complexity of the password, and it usually takes a long time.

If it is a BIOS password, directly pull the motherboard battery, and then use tweezers to short (contact) the positive and negative poles, and then install the battery.

If it's a laptop, the TV is soldered to the motherboard, then it's no problem.

Press F8 to enter safe mode when you first turn it on.

Make a USB flash drive boot, which can crack the password.

You can crack it, but you can't know your dad's password ......

First: Ask my dad and ask him to help open it, which is a more secure method.

1. Restart Windows, press F8 at the moment after the boot screen appears, and select "Safe Mode with Command Line" to run.

2. When the running process is stopped, the system lists the selection menus of the superuser administrator and the local user owner, and clicks the administrator to enter the command line mode.

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

If the username 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 user of the system administration group with super permissions.

You can delete the SAM file in Windows System32 Config.

5.After powering on, press the delete key of the keyboard to enter the BIOS interface. Find the user password option, which is off by default.

Activate and enter the user password (1 8 digits, English or numbers). The computer prompts you to enter it again to confirm that the password is correct, save and exit and restart the machine, and the password menu will appear when the computer is turned on.

Hope it helps!

Me too!! Parents are so ruthless!
