Although passwords can increase the security of the system, it is a pain to repeat passwords every day for faster and faster life and work. If you can consider the security factors and the convenience of use, how to automatically log in without changing the password when the login password is set? Or how to ensure the security of the system without logging in with a password? The following system home will tell you how to avoid the password entry. Home computer users do not like to set the Windows power-on password. Since it is very troublesome to enter the password every time, everyone often likes to boot directly into the desktop or press a carriage return to enter the system. Therefore, many people do not set any passwords when they install the system. However, without setting a password, others may easily log in to their systems through a remote connection, posing a potential hazard to system security. In fact, whether it is password-free and password-free, or no password at all, we can find a solution to ensure security. Windows XP free password security login modify the registry Press Win + R key combination to start the run window, enter regedit to start the registry editor, expand the [HKEY_LOCAL_MACHINE\\SOFTWARE \\Microsoft\\Windows NT\\CurrentVersion\\Winlogon] branch (Figure 1), Double-click DefaultUserName in the right window and enter the login user name. Also double-click DefaultPassword in the right window under the branch and enter your password in the blank field. If you don't have this item, you can add it by right-clicking the menu “New → String Value →DefaultPassword”” in the right window of the Registry Editor. Next, double-click AutoAdminLogon in the right window to set the value to 1. If you do not find this item, you can create it by following the steps above. Finally, close the registry editor and restart the computer, the system will automatically log in according to the set user name and password, and will not remind you to enter the password after booting. Run the command to enter the rundll32 netplwiz.dll, UsersRunDll command (Figure 2) in the "Run" window, press the Enter key to pop up the "User Account" window. Deselected “To use this machine, the user must enter the username and password" option, click “OK> (Figure 3). To change the automatic login password, press Ctrl+Alt+Del and enter the account and password you want the computer to automatically log in each time in the pop-up dialog box. In addition, it can be implemented with the system control command. Click “Start →Run” and type the control userpasswords2 command in the input box (Figure 4), and then follow the same operation as Method 2. Can Windows 8 automatically and securely log in with a password? Compared with Windows XP, Windows 7 and Windows 8 have changed a lot from interface to function. So, can you still use the old one for the setting of the password-free automatic login system? We can get the verification through experimentation. I am using Windows 8, here I directly verify the Windows 8 environment, the Windows 7 environment is left for you to verify. Use the shortcut key Win+R to open the Win8“Run” dialog box, enter rundll32 netplwiz.dll, UsersRunDll command and press Enter, open the “User Account” window, and “To use this computer, the user must enter the username and password. ” Check the box to cancel (Figure 5), restart the computer and found that Windows 8 has been able to log in automatically. Then open the Windows 8 “ Run & rdquo; dialog box, execute the control userpasswords2 command, also follow the experiment window, restart the computer and find that Windows 8 can also automatically log in without manually entering the password. Finally, look at whether Windows 8 automatic login can be achieved by modifying the registry. First press Win+R, then enter the regedit command to enter, enter the Windows 8 registry settings interface, and locate the [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon] item. Find the AutoAdminilogon entry, set the key value to 1; find the DefaultUserName entry, set its value to the username that requires automatic login; create a new DefaultPassword string value with the value set to the password for the username (Figure 6). Close the registry editor, restart the computer, and find that password-free automatic login is also possible. It can be seen that Windows 8 can still use a similar method to achieve secure automatic login settings for accounts. There is no way to log in. There is still a way to change the security. If you do not set a password, you can prevent remote intrusion by remotely accessing the computer. Take Windows 7 as an example. From the control panel settings: along the "Control Panel & Rarr; System and Security & Rarr; System & Rarr; Advanced System Settings & Rarr; Remote & rdquo; path operation, remove the "Remote Assistance: Allow Remote Assistance to connect this computer" Select and select "Remote Desktop: Do not allow connection to this computer", and finally determine (Figure 7) and then use Group Policy to achieve control: execute the gpedit.msc command in the "Run" window, along the "Computer Configure → Windows Settings & Rarr; Security Settings & Rarr; Local Policies & Rarr; Security Options & rdquo; Path Operation, double-click "Account: Local Account with Empty Password Only Allows Console Login" Set to “ Enabled & rdquo; Status ( Figure 8). Tip: Users of Windows 8 can cancel the “Allow remote assistance to connect to this computer” option in the “System Properties” window and select “Don't allow remote connections to this computer” to block remote access. .
