Locking the computer is to lock the operation interface of the current user and return to the system login screen. If you don't have a boot passcode, you don't need to enter it when you wake up. If you set a password to lock the computer, the password is the password to use the computer.

The shortcut key to lock Windows is Win+L. This locking method is not limited to laptops or desktops, and the Windows operating system is effective. The Windows key is the silly noise between Ctrl and Alt on the left side of the keyboard.

It looks like a small flag.

On the old keyboard was Windows 95 and Windows 98 Windows graphics, and the modern keyboard (from Windows XP) used the new Windows logo as the logo of the keyboard Windows key, which is actually the logo of the Windows system.

You can right-click on your desktop --- properties--- screen saver (select "None" below) - uncheck the box before "Password protect when recovering" and click "OK".

The following example is used to restore the ZDC password of a local user 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 "zdc", and clicks "administrator" to enter the command line mode.

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

2. Use "administrator".

In the process of installing Windows XP, first log in with "Administrator" by default, and then ask to create a new account, so that you 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 we 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 will appear, at this time, type "administrator" in the user name, the password is empty to enter, and then modify the password of "zdc".

Isn't shift+del a key combination for direct deletion? How do you lock out the computer user?

1.Click "Start Run", enter "rundll32 ,usersrundll", press the enter key and the "User Account" window will pop up, see clearly, this is different from the "User Account" panel window opened in the "Control Panel"! Then uncheck the "To use the machine, the user must enter a username and password" option, click OK, and enter the account and password you want the computer to automatically log in to each time in the pop-up dialog box.

2.Click "Start" and "Run" and enter "regedit" to open the registry. Then click on the "hkey local machine software, Microsoft Windows NT NT CurrentVersion, Winlogon" branch, then double-click on "DefaultUsername" in the right window, and then enter your login username.

If you don't have a preset username, you can add this item by clicking "New String Value(s) defaultusername" in the menu bar of the registry, noting that it is case-sensitive. Also under this branch, double-click on "defaultpassword" in the right window of the registry and enter your password in the blank field. Next, double-click "autoadminlogon" in the right window and set the value to "1".

If you do not find defaultpassword and autoadminlogon, you can create a new string value by following the steps above. Now close the registry and restart the computer, and later you will find that annoying login dialog is gone.

Method Steps:

1. Right-click "Desktop" and select "Properties" in the pop-up right-click menu.

2. In the "Properties" window that opens, switch to the "Screen Saver" tab and uncheck the "Use protection password on recovery" option.

Locking your computer is all about helping to protect your computer, and you should log out or lock your computer when you leave.

After you log out of your computer, other users can still log in to your computer. However, when you lock your computer, only you or your administrator can log in. What's more, when you unlock and log back into your computer, the open files and running programs are ready to use immediately.

A password-protected screen saver provides another level of protection that prevents other users from viewing the screen and using your computer while you're away.

Locking the computer is to lock the current user's interface!! So what are you doing now, are you done, but something is out again!! You can lock your computer or others will see what you're doing!

And when you come back, you can just enter the password and you can continue what you didn't finish doing.
