Vista username password, Vista password forgotten

Are you an administrator in the first place? Did you log in with administrator? If you don't restart your computer and go into safe mode, then you're logged in as an administrator, and then you go to the user account and change the account you have a password for, and if you really don't remember the password, you can also delete the account and then open the administrator or create a new login account.

If you are an administrator and have forgotten your password, here's how:

Please first put the Vista installation disk into the optical drive, restart the computer, and set it up in CMOS to boot the optical drive.

1.When the installation screen appears, click "Repair Your Computer" and select "Command Prompt" in the dialog box that pops up.

2.After invoking the system's command prompt window, enter the command and press enter, and the system will call out the console.

3.Then select File -Add Remove snap-in and a dialog box will pop up again. Select Local Users and Groups in the left window of the dialog box, and then click the Add button.

At this point, the system will add Local Users and Groups to the Console Node, and click the OK button to complete the addition process.

4.After the addition is complete, return to the console operation page, click Local Users and Groups in the left window, and then click Users, and the system will list all the current users in the right window. Right-click the logged-in user you want to hack, select "Set Password", and in the pop-up "Set Password for Account" dialog box, click "Continue Button".

5.A new password window pops up. At this time, the Vista system does not require the user to enter the previous password, but can directly set a new password. After entering a new password, click the OK button, and a dialog box will pop up to say that the setting is successful.

Then just fill in the password you set, and don't tell me that you entered the password yourself but forgot it.

If the username is not set, then it will be a space.

This is more troublesome because you need to dos the operation. You need to delete a file from your system. If you don't have an installation disk, you can find someone who understands the computer and borrow a disk that has a system, which can be started directly from the disc.

This close disk can not only be installed with the system, but also can be directly used with the Windows PE system on the CD, after the PE system enters, find it.

If the desktop forgets the boot password (not the system login password), it is feasible to discharge the BIOS chip retainer battery. I don't know if it's feasible to plug and unplug the memory upstairs.

If you have forgotten your system login password, you can:

The following example is used to restore the password of a local user "hfr0724" to illustrate the steps to solve the problem of forgetting the login 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 hfr0724 123456 add" to force the password of the "hfr0724" user 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 "HFR0724" user with the changed password "123456".

Method 2: Clean SAM files.

Winnt system account information is stored in the registry file %systemroot% system32 config sam. If there are no important accounts in the system, or there are few accounts, it is relatively simple to delete %systemroot% system32 config sam, but because the system will be restored to only the administrator (the password is empty) and the guest account, some programs because the accounts they rely on are lost, such as IIS and VMware, can not be started.

The other methods are more troublesome than these two. Good luck!

1. Please use the system that comes with the system, and restore the false error to repair when you do not have this failure (if the normal mode recovery fails, please boot the computer and press F8 to enter the safe mode to use the system restore).

2. If the fault persists, use the system disk to fix it, open the command prompt and enter sfc

scannow

Press enter (there is a space between SFC and ), insert the original system disk to repair the system, and the system will automatically compare the repaired one.

3. If the fault persists, set the optical drive in the BIOS as the first boot device, insert it into the system installation disk, press the R button, and select "Repair Installation".

4. If the fault persists, it is recommended to reinstall the operating system.

Open the control panel and click in order: User Account - change the way to log in or log out with Mu Pi Household, then check "Use Welcome Screen" and "Use User Yuyuan Quick Switch", and then click on the application option.

Method 1:

1. Restart the computer, press the F8 button after booting up and not moving until the advanced options screen appears, then release your hand and select "Safe Mode of Command Prompt" to enter.

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

3. Type the command: "net user **123456 add" to force the password of "**user" 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 ** user with the changed password "123456".

Method 2: Use Windows XP system to install a disc to repair the system and crack the super computer administrator password.

Step 1: Set the system to boot on a disc and put in the system installation disc. Press Enter when the first selection screen appears, and press the "R" key to start the repair installation when the second selection screen appears.

The installer then checks the disk and starts copying the files. Once the file is copied, the system will automatically restart.

Step 2: After restarting, the system will enter a graphical installation interface. Note:

At this point, you should keep an eye on the bottom left corner of the interface, and press the key combination "Shift+F10" as soon as the "Installing device" progress bar appears. Then something unexpected happens, and a command prompt window appears in front of us. This is the key to cracking the code.

Step 3: Type 'Local Users and Groups' management tool in the command prompt window and press enter (without double quotes). Click "Users" on the left, then right-click on the administrator account on the right, and select "Set Password".

At this point, a warning window pops up. Roughly speaking, after changing the password, some information in the system will become inaccessible. This mainly refers to files that have been encrypted with EFS and have not exported a certificate before, and these files will not be accessible after changing the password.

If I didn't have this kind of file, I just ignored it and just clicked "Continue", then entered the new password, and clicked OK. Then close the Local Users and Groups and Command Prompt windows and proceed to complete the repair installation. Once the installation is complete, the system administrator account is "activated" again.
