The role of the Windows screen saver password is mainly when you temporarily leave the computer, do not want to shut down, and I am afraid that someone will take the opportunity to see what you are doing or tamper with you on your computer. The screen protector password can play a certain role, and it is slightly better than the user password. If the password is wrong, it is very difficult to pass.

Let's first take a look at how to set the screen saver password. First click on the mouse in the blank space and select the "Properties" command from the shortcut menu. The "Display Properties" dialog box will open, which has "Background", "Screen Saver", "Appearance", "Effect". "," "Web", "Settings" six tab items. Clicking on the "Screen Saver Tab" will open the "Display Properties". In the "Screen Saver" drop-down list box of this window, there are various screen savers that come with Windows. When we select a screen saver from it, Click “Preview” and the screen saver will appear. Click “Preview” to display it in full screen (return by clicking the mouse). The “Settings” button allows you to set the display of the screen saver. You can enter or adjust the time to start the screen saver in the “Wait” spin box. Even more tempting is that the screen saver has some security features! If you want to be unable to use your computer when you are away, the easiest way is to enable the password function of the screen saver, check the "Password Protection" box, click the "Change" button and a "Change Password" dialog will appear. Box, then enter the password twice and confirm it.

If

I accidentally forgot the password of the screen saver, what should I do? Direct shutdown? That's too savage; and, if your work is not saved, don't you give up! Now, as long as you know the IP address of your machine, using this method, your problem will be solved!

In fact, the method is very simple. First, use another machine as the decoder in the LAN where your machine is located. Change the IP address of the decoder to your IP address, and use the priority of hardware conflicts. The high principle allows the operating system to skip the screen saver.

The specific implementation method is as follows:

On the decoder, find the "Settings" item in the "Start Menu", click "Control Panel", enter the "Control Panel", double-click "Network" "" icon, enter the "Network" dialog box.

Select the "Configuration" tab, then double-click "TCP/IP", enter the "TCP /IP Properties" dialog box, select the "IP Address" tab, change the IP address of the decoder to your IP Address, click the "OK" button when done.

You will be prompted for new settings to restart your computer to take effect, confirm and restart your computer.

Thus, the IP addresses of the two machines in the LAN are the same. When the startup of the decoder is completed, the "IP address generates hardware conflict" prompt box will be displayed on both your machine and the decoder. At this time, just click OK on your machine and guess what happens? That's right, the system does not require you to enter the password of the screen saver, just enter the operating system's desktop!

You don't have to worry about forgetting your password? However, it is worth noting that during the entire cracking process, make sure that there is no dialog box on your machine requesting the input of the screen saver password. Otherwise, after determining the hardware conflict, the system will continue to ask you to enter the password of the screen saver.

The system's screen saver password is very fragile. We just use the "Reset" button to force the computer to start after forgetting the password (some screens with imperfect design can even be closed with Ctrl+Alt+Del, the operation is much simpler), then right click on the blank space on the desktop and from dan Execute the "Properties" command in the shortcut menu, open the "Display Properties" setting box and click the "Screen Protection" tab, and finally cancel the "Password Protection" option (you do not need to confirm the password when canceling this option).

Here is a more convenient way to tell everyone. As you all know, the screen saver password can be up to 16 characters. Microsoft built a 16-byte key: 48 EE 76 1D 67 69 A1 1B 7A 8C 47 F8 54 95 97 5F. Windows encrypts the password you entered with the above key. The encryption process is as follows: first, convert the password characters you input into bits by bit to their hexadecimal ASCII code values ​​(lowercase letters are first converted to uppercase letters), and then XOR the bits with the corresponding keys in turn, and get the resulting 16 Each bit of the hexadecimal value is treated as a character, converted to its hexadecimal ASCII code, and 00 is added as an end mark at the end thereof, and stored in the binary key ScreenSave_Data under the registry HKEY_CURRENT_USER\\Control Panel\\desktop. So delete the ciphertext of the Windows screen saver password stored under the HKEY_CURRENT_USERS\\ControlPanel\\Desktop\\ScreenSave_Data primary key in the registry.

In addition, there is also a CD on the market dedicated to cracking the screen saver password. After inserting the CD, it will use the autorun function of Windows 98 to start the screen saver password cracking program saved on the CD, analyze and decipher the password of the screen saver function, and finally display the password on the screen or write to the floppy disk. This is more convenient. Recommended Articles
