The account has a password, how to cancel it

The password of Windows XP is stored in the SAM file under Windows System32 Config where the system is located, and the SAM file is the password database file. When we log in to the system, the system will automatically check with the SAM in the config, if we find that the password and username are all consistent with the encrypted data in the SAM file, you will log in smoothly; If there is an error, you cannot log in. In the 2000 system, it is possible to recover the password by deleting the sam file, however, deleting the sam file directly in the xp will make the system unable to log in normally, the best way is to find c:

The SAM file in WindowsEPair is overwritten to WinNT System32 Config, of course, it is best to back up the original SAM file first, so that it can be restored in case of problems.

If you don't care about any of the operating systems contained in the original system, and there are two operating systems, you can use another operating system that can access NTFS to boot the computer, or although you do not have two systems installed, you can use other methods such as using the 98 boot disk to access from under DOS, if it is an NTFS partition, you can use some tools to access, and then overwrite the SAM file in the C: Winnt system32 config directory and restart. At this point, the administrator does not have a password.

Of course, it is also possible to remove the hard drive and replace it with another machine to overwrite the SAM files.

Tip: Windows NT 2000 XP uses the security manager (SAM) mechanism for the security management of user accounts, and the management of the security manager pair is carried out through the security identity, which is created at the same time when the security identity is created, and once deleted, the security identity is also deleted at the same time. Security identities are unique, and even if they are the same username, they are completely different each time they are created.

Therefore, once a security identity is deleted, it no longer exists, and even if it is rebuilt with the same username, it will be given a different security identity without retaining the original permissions

The Security Manager is the %systemroot% system32 config sam file. The SAM file is a Windows NT 2000 XP user account database, and all user logins and passwords are stored in this file.

But this is only a palliative solution, to solve this problem completely, you should master the administrator password yourself, only give the user permission to the student, so that they can not change the administrator password, or create a domain, with a domain administrator account can log in to any machine in the domain.

It's only 27K in size, copy it to a DOS boot disk or boot USB flash drive, here's how to clean it:

1.Start with a floppy disk or USB flash drive, run, enter 1 in your chioce:[ position, press enter; Then display the hard disk partition table, press enter; Then it shows that the disk MS SAM was detected

database, press enter. Next, a new window will appear, showing all users in the system, enter the administrator serial number to be cracked in "your choince:[ , and press Enter.

2.Enter in the prompt that appears"y"Enter. After a while, you will be prompted that the password has been successfully cracked.

3.Restart your computer and log in without entering your administrator password!

Open "User Account" and you can see that the administrator password has been removed.

This method can be achieved without any advanced technology, and it is easy to learn and use.

A good way: is to press the F8 key when the system starts, enter the safe mode, you will find that there is one more account than the general login, and that is the account of the highest administrator, you will find that you do not use the password when you enter that account, and then you can enter the control panel to change the password.

There are 2 ways, 1: If you don't enter the security mode, click on the one that doesn't use the password, and cancel the password in it. 2: Remove the battery from the motherboard, install it again, and there will be no password.

All of the above is a garbage method that spreads everywhere on the Internet.

Tell you a practical one, from the new installation of a new system.

Install the restore card, create an administrator account, and set the password yourself.

Create another ordinary account, and the password cannot be changed for the ordinary account.

In general, they are not changing the administrator's password. So you just need to boot the computer into safe mode and log in with administrator. Then delete their account in the control panel.

You try the administrator account, can you enter if the password is empty?

If you can enter, after entering, right-click on my computer to select management, and set the account to empty.

By the way, you can post it in the future work, and do a check before they leave, that is, you clear the password!

I agree to add a restore card, which is more practical, and the administrator has to slowly change the password by himself every time, and after installing a restore card, restore some of the settings of others, which is more secure.

You can enter safe mode! If not, post a notice asking for a password! Or it's going to smack, public! Sell parts!

As far as I know, there is only a reinstall system

If you have forgotten your password, you can try the following methods to solve the problem:

1.Use the "Forgot Password" option: If you provided an alternate email address or ** number when setting up your password, you can try using the "Forgot Password" option to reset your password.

Provide them with your account details and describe your problem, and they may be able to provide you with further guidance and support.

3.Try using a backup account: If you have a backup account set up, you can try logging in with that account and reset your password from there or have other verification methods available.

Please note that the exact method of deactivating your password may vary depending on the service and system. You will need to carefully read the help documentation of the relevant service or contact their support team for an exact solution.
