Five Windows password settings and cracked _windows2003

In the process of using the computer, it is inevitable to deal with various types of passwords, the following nine kinds of passwords may be the most used by everyone: BIOS password, installation password, user password, power management password, screensaver password, power-on password, internet password, graded audit password and shared password. Today, we will talk about these and we are closely related to the password, this article first of nine common password of the first five kinds of password.

　　First, the BIOS password　

The BIOS (basic Input output system), the basic input/output, is actually a set of programs that are solidified into a ROM chip on the computer's motherboard to provide the lowest-level, most direct hardware control for the computer. Unlike other programs, the BIOS is stored in the BIOS chip, not stored on the disk, because it is part of the motherboard, so people sometimes call it a different from the software is also different from the hardware name "firmware" (firmware), which is mainly used to store the Self Diagnostic test program ( Post programs, System bootstrap loader, System Setup program, and I/O drivers for primary I/O devices and interrupt service programs.

If you do not want others to use their own computer, you can set the BIOS password to the computer to add a "lock." What should I do if I forget my bios password? Don't worry, here are a few tips to help you.

Depending on the user settings, the boot password is generally divided into two different situations, one is the setup password (in this way, the system can be started directly, but only enter the BIOS settings required to enter the password); the other is the system password (in this way, Either direct or BIOS setup requires a password, no password will accomplish nothing. For the two passwords set by the user, our methods of cracking are different:

　　(i) Cracking the setup password

If the computer can boot properly, but cannot enter the BIOS setup (that is, the setup password is set), then we have the following options:

　method One: Dubug method

After you forget your password, just start debug in DOS, and then type the following command to manually clear the password:

_ O 70 16

_ O 71 16

_ Q

In addition, users who are unfamiliar with debug can also download a tool software cmospwd that specifically cracked the CMOS password. The program is then launched in DOS, and it will display the user's CMOS password (CMOSPWD supports Acer, AMI, award, COMPAQ, DELL, IBM, PACKARD BELL, PHOENIX, ZENITH ami, and many other bios). Very convenient to use.

method Two: Software cracked

Now have a lot of detection system or power-on password software, the most common have biospwds, cmospwd and so on. Biospwds is one of the most excellent one, you can detect the BIOS version, BIOS update date, Administrator password, CMOS password, password type, and so on, and the use of simple, click the window "Get Password" button to display all the information Biospwds detected.

But because the software cracked the password, is the BIOS encoded password reverse decoding, so sometimes may find the program's password and the real password is not the same, this is also a normal phenomenon, so this trick sometimes will not spirit.

　　Method Three: Oneself compiles the document to crack

Enter the MS-DOS environment and enter edit and carriage returns under the DOS prompt (if you find that you have not edit.com the file by clicking Edit, please see the next method) and enter:

ALT+179 ALT+55 ALT+136 ALT+216 ALT+230 ALT+112 ALT+176 ALT+32 ALT+230 ALT+113 ALT+254 ALT+195 ALT+128 ALT+251 ALT+64 ALT+1 alt+241 alt+195

Note: Enter the above data first press the ALT key, and then press the numeric keypad (press the keyboard above the row of the number key is not the role of the number key), after the loss of a number of digits and then release the ALT key, and then press the ALT key. During the operation, a random character appears on the screen and we don't have to worry about it. Then select "Save" under the "File" menu and save it as a cmos.com file, then exit to the MS-DOS environment, find cmos.com This file, see if he is 20 bytes, if it means you entered the wrong, you need to re-enter. After confirmation, directly run cmos.com, the screen should not have any hint information, and then restart the computer to clear the CMOS password, of course, the other CMOS settings will also be cleared, which requires us to reset.

　　Method Four: dos under the crack

This method can be done directly in MS-DOS and entered in MS-DOS: COPY CON CMOS. COM after return, continue to enter the following 10 characters: alt+176 alt+17 alt+230 p alt+176 alt+20 alt+230 Q alt+205 < space, and then press the "F6" key, and then press ENTER to save, After running the cmos.com file, reboot.

_info.asp?id=12392 "Width=1 border=0> (ii) cracked system password

Without a password to start the computer at all (that is, the system password is set), we cannot solve the problem of password forgetting by software. At this point you can use the following methods:

　　The first trick: universal password

Each motherboard manufacturer has a common password set by the motherboard to facilitate technical support. If we know the common password for the motherboard, then either open

Machine, or CMOS settings can be "through the wall into" of course, do not use this to do bad things yo!

It is important to note that the motherboard manufacturers for some reason, different times the general password of the motherboard will be different, so this trick and can not pass the world, we only try a few times, whether it is useful depends on luck!

Award BIOS Common password: j256, Lkwppeter, Wantgirl, EBBB, Syxz, ALLy, AWARD?SW, AWARD_SW, j262, HLT, SER, Sky_fox, Biostar, Alfarome, Lkwpeter, 589721, Awkard, h996, CONCAT, 589589.

AWI BIOS Common password: AMI, bios, PASSWORD, HEWITT RAND, AMI_SW, Lkwpeter, A.M.I.

　The second trick: CMOS discharge

Most of the current motherboards use button batteries to provide power to the BIOS, which means that if there is no electricity, the information inside it will be lost. When it is again on the power, the BIOS will return to the original state not set, of course, the BIOS password is not.

First we need to open the computer chassis to find the Silver button battery on the motherboard. Carefully remove it, and then the chassis rear power plug unplugged, with a metal plate short to the bottom of the battery to sit on the spring, about 30 seconds after the battery installed.

At this time the CMOS will lose the internal storage information because of power loss, ok! Put it back, close the chassis to boot, the system will be prompted "CMOS Checksum error-defaults Loaded", that is to prompt you "CMOS detected errors in the inspection, has loaded the system defaults" BIOS password cracked successfully.

　　The third recruit: jumper short connection

If the motherboard of the CMOS chip and battery integrated in a piece, or the battery is directly welded to die in the motherboard, there is the second we use the "CMOS discharge method", the results did not work, then we will use jumper short to take this trick.

After opening the chassis, there will be a jumper switch near the motherboard CMOS battery, with reset CMOS (reset CMOS), clean CMOS (clear CMOS), CMOS close (CMOS off), or CMOS RAM reset next to the jumper ( CMOS memory reset), and so on, with the jumper cap short, and then jump back on the line!

Because the different motherboard jumper settings are not the same, so in the use of this trick, it is best to first consult the motherboard instructions. Forget to say one thing, when the CMOS discharge or clear the data in the CMOS, do not in the case of system boot, it is recommended to cut off the computer power.

　　 Second, the installation password of Windows

First talk about installing the password. The install password, Windows CDKEY, is required to install Windows, and is recorded in the registry when it is finished. Click "Run" under the "Start" menu, enter regedit to open Registry Editor, you will find the installation password of Windows in the following registry location: Hkey_local_machine\software\

Microsoft\windows\currentversion\productid and Hkey_local_ Machine\software\microsoft\windows\currentversion\productkey, if you forget the installation password for Windows One day, come here and find out. In fact, the password is not important, it is only useful when reinstalling Windows and is automatically recorded after installation. If you are reinstalling Windows and you do not have a password installed, you may want to check in here and record it for later use.

Third, the user password

About the user password, many people have an erroneous zone, that is, the user password is the power-on password. In fact, Windows does not have a power-on password by default. So what is the user password for? is used to protect the "personality"! The system allows multiple users to be set up and is not intended to protect users ' privacy. Instead, each user is saved with a set of system appearance configurations to accommodate different user habits, just like the current "skin", just to enter a password. So this password does not play a role in secrecy, just a device.

The user password can be set in the Password or User tool in Control Panel: In the Control Panel, double-click the "User" icon, click the "New" button, the "Add User" window, click "Next" button, enter the new user name, and then click "Next", in the window that appears to enter a new user password, Then click the "Next" button, the "Personalized Settings" window will appear, select the item you want (not optional), and then click the "Next" button, you can add a new user for this machine. Use the same method to create a username for each user who can use the machine, and then you can enter the password and, of course, leave it to the user to change the password after logging in.

People who have a little knowledge of Windows know that in a Windows 9X system, there is no security to this cryptographic system. It in the boot or change the user to start when landing, enter the correct password can use the system, but even do not know the password can also use ESC key to skip the landing procedures, direct access to the system. We can then change the registry to force the user to enter the user name and password at the time of the power-on to enter Windows. Implementation: Click "Run" in the "Start" menu, enter regedit, open Registry Editor, turn to Hkey_local_machine\network\logon, and then create a new DWORD value named " Mustbevalidated ", the value is changed to 1, it is OK.

Unlike Windows 9X, Windows 2000 has made great improvements in this area, if the system is set to: Users must enter a user name and password to use the computer, if not entered the correct username password can not enter the system, while the user divided into managers, users and guests three categories, Each has its own different permissions. This provides a means for standardizing the management of computer users.

In addition, users who are familiar with the Windows 9x system know that the user password information is stored in a file with the extension ". PWL" in the Windows directory. Here's a simple and effective way to protect yourself: click "Start" → "Run", enter the Sysedit command, and open the System Configuration Utility. Select the file System.ini file. At this point you will notice that there is an item in the list item titled [Password Lists], which is the link record for the user's password file, where SSJ=C:\WINDOWS\SSJ.PWL (the "SSJ" before the equal sign is the username, After the equals sign is the path and filename of the user's password file. Knowing this, we can modify it to arbitrarily specify the file. For example, you can rename the source file Ssj.pwl in advance and copy it to another directory, such as in DOS, execute the command: Copy C:\WINDOWS\SSJ.PWL C:\WINDOWS\SYSTEM\S1.DAT. And then the System.ini of the password file in the store path to Ssj=c:\windows\system\s1.dat. In this way, no one can easily find your password file.

What happens if the user password for Windows is forgotten? Be assured that this will not affect the system's startup, but it will cause users to be unable to enter their personal settings, so it is necessary to crack the Windows startup password in order to retrieve the lost "personality". To do this, we can delete the * from the Windows installation directory. PWL password file and all the personal information files in the Profiles subdirectory, and then restart Windows, the system will pop up a password setting box without any user name, we do not need to enter any content, directly click the "OK" button, the Windows password is deleted. In addition, modifying the Userprofiles under the registry Hkey_local_machine\network\logon Branch to "0", and then restarting Windows can achieve the same purpose.

　Four, the Power management password

Windows Power management features can also set the password, set this feature, when the system returns from the energy-saving state will require a password, then users who do not know the password can not make the computer from the "suspend" state back to normal state, which further guarantees the security of the computer data.

To set a password for the Power management feature in Windows 98, do the following:

1, click

Start button, and then select settings → control Panel to start the Windows 98 Control Panel.

2. Double-click the Power Management icon in Control Panel to open the Power Management properties setting box.

3. From the Power Management Properties Setting box, select the Advanced tab.

4, in the "computer out of standby, prompted to enter the password" option before the "√".

5, select the Power Scheme tab in the Power Management properties Settings box.

6. In the System Wait Status list box, select the time interval in which the computer automatically starts the Power management feature (that is, the "suspend" state) after it has not been operated, with different options such as "from 1 minutes later" to "never", and users can choose for themselves.

7, for "Turn off the Monitor" and "turn off the hard disk" set the appropriate time interval.

8, click "OK" button, turn off the "Power Management Properties" setting box.

This allows us to start the Power management feature of Windows 98 and set the appropriate password for it. Notably, the password for the Windows 98 Power Management feature is based on the user's password for Windows 98 itself, which means that we must first set the user's password for Windows 98 before using its power Management password feature, otherwise it will not work. In addition, the Windows 98 Power Management feature does not have a separate password, and its password is exactly the same as the Windows 98 user password, which eliminates the inconvenience of users remembering multiple passwords at the same time. But from another point of view, the power management function of the password and the user password exactly the same, will be very insecure, we just follow the previous method to crack the Windows user password, the power management password will be the same.

_info.asp?id=12392 "Width=1 border=0> five, screensaver password

Let's talk about the screensaver password next. The main function of it is that you leave the computer temporarily, do not want to shut down, but also afraid of someone at this time in your computer to see what you are doing or moving your machine, at this time the screensaver password can play a certain role in protection, and it than the user password than the user password a little better than the word. If the password is not correct, it is difficult to pass.

Let's take a look at how the screensaver password is set. First in the desktop space

Right-clicking, and selecting Properties from the shortcut menu, opens the Display Properties dialog box, which has the background, screen saver, appearance, effects, Web, settings, six label items on the dialog box. Clicking on the "Screen Saver tab" will open "Display Properties". The Screen saver drop-down list box in the window has a variety of screen savers that are included with Windows, and when we select some kind of screen saver, clicking Preview will result in a screen saver, click Preview It can also be displayed in full screen (the mouse click will restore). The Settings button sets the display of the screen saver so that you can enter or adjust the time to start the screen saver in the wait spinner. More appealing is that the screen saver also has a certain secrecy function! If you want someone else to be unable to use the computer while you're away, the easiest way to do this is to enable the password feature of the screen saver, check the Password protection box, click the "Change" button to appear a "Change Password" dialog box, and then enter the password two times and confirm it.

What if you accidentally forget your screen saver password? Direct shutdown? That would be barbaric, and if your work had not been saved, it would be naught! Now, as long as you know the IP address of your machine, use the following method, your problem will be solved!

In fact, the method is very simple, first of all, in your machine in the local area network using another machine as a decoder, will be the IP address of the decoder to your IP address, the use of the high priority of hardware conflicts can make the _blank> operating system Skip screen saver.

The implementation methods are as follows:

On this decoder, locate the settings item in the Start menu, click Control Panel, go to Control Panel, double-click the Network icon, and go to the Network dialog box.

Select the Configuration tab, double-click TCP/IP, go to the TCP/IP Properties dialog box, select the IP Address tab, change the IP address of the decoder to your IP address, and then click OK when you are done.

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

In this way, there are two machines in the LAN IP address is the same. When the decoder is completed, on your machine and decoder will also pop-up "IP address generated hardware conflict" prompt box, then just click on your machine to determine, guess what will happen? Yes, the system does not require you to enter the screen saver password, directly into the _blank> operating system desktop!

You don't have to worry about forgetting your password? It is worth noting, however, that during the entire cracking process, make sure that your machine does not request a dialog box to enter the screensaver password, or that the system will continue to require you to enter the screen saver password after the hardware conflict.

The system's screen saver password is very fragile. We simply use the "reset" key after forgetting the password to force the computer to start (some imperfect screen saver can even be forcibly closed using Ctrl+alt+del, the operation is simpler), and then right-click the desktop space and execute the Properties command from the pop-up shortcut menu to open the show properties Settings box and click the Screen Saver tab, and then remove the password protection option (no need to confirm the password when canceling this option).

Here is a more convenient way to tell you. As you all know, the screen saver password is up to 16 characters. Microsoft has a built-in 16-byte key: 1D-EE-A1 1 b 7A 8C F8 5F. Windows encrypts the password you entered with this key. The encryption process is: first converts the password character you entered into its 16-Ascⅱ code value (lowercase letters first to uppercase letters), in turn, the corresponding key is bitwise-per-bit, and each digit of the resulting 16 value is converted to its 16 ASCII code as a character, And in its tail plus 00 as the end sign, into the registry HKEY_CURRENT_USER\Control Panel\Desktop under the binary key Screensave_data. So put in the registry of the Hkey_current_users\controlpanel\desktop\screensave_data primary key of the Windows screensaver password ciphertext, delete it!

In addition, there is also a special type of optical disk used to crack the screen protection password. After inserting the disc, it will use the Windows 98 Autorun function to start the screen protection password cracking program saved on the CD, analyze and decipher the password of the screen protection function, and then display the password on the screen or write to the floppy disk, which is more convenient.

About the screensaver password There is also a worry-some friends always like to tinker with the computer, often to screen protection settings password, if it is their own home, if it is the school room or the computer in the Street Café, it is a bit of trouble. Have this screensaver password annoying friend don't worry, we can screen protect the function of the password to shield, so that it can not set the password, so that the problem could be solved. The specific operation methods are as follows: Click the "start" → "Run" menu, in the Open "Run" dialog box input regedit, enter, open the Registry Editor, find Hkey_current_ User\controlpanel\desktop\screensaveusepassword (if there is no "screensaveusepassword" to create this DWORD value, the method is: Right click on "desktop", Select "New" → "DWORD value" in the pop-up menu, and name it "Screensaveusepassword", that is, this key determines whether the screen saver uses a password, its key value is 0 or 1, the "0" means no password, and "1" Indicates that a preset password is used. We change this value to "0" to prevent the screen saver from using the password.
