Introducing the window xp system/2000 system little-known security command

There are many little-known functions in the system, but these functions are especially powerful except for the secret. Today, this tutorial introduces such a function. . On Windows XP and Windows 2000, there is a command that I don't usually use, but that is powerful, and that is: the syskey command.

This command can effectively enhance your system security. Maybe you have to say that you have to enter your account and password when you enter Windows XP or Windows 2000. Isn't this safe? The famous WIN 2000 input method vulnerability you should have heard of

If your computer is used by multiple people, others can access the system by breaking someone else's simple password and use various vulnerabilities to gain administrator privileges. With the encrypted floppy disk made by syskey, you can use 2000 and XP with complete peace of mind. Let's take a look at the usage of the syskey command.

First, double password protection settings

1. In the Start menu, click "Run", enter "ldquo; syskey", click OK.

2. The account database mentioned in this interface is the principle of NTFS encryption. For our general users, we do not need to study the principle, we just need to use it. Next click on “Update”.

3. Here we select the password to start, enter a password, and then click OK. Doing so will make WINXP need to enter the password more than once, which will serve as the encryption twice. When the operating system starts, we will display a window prompt before entering the user name and password. “This computer needs a password to start, please enter the startup password”. This is the first password protection we have just created.

Second, the production of password floppy disk

1. If we choose "Save the startup password on the floppy disk", this will generate a password floppy disk, without this floppy disk, no one wants Enter your operating system. Of course, if you have previously set the syskey system startup password, you will need to enter the password again to get the corresponding authorization. This is similar to the way we change the QQ password, we must know the original The same password.

2. Then the system will prompt you to put a floppy disk in the floppy disk drive, and a prompt will appear when the password floppy disk is generated.

3. Then we start the system again, then the system will prompt you to insert the password floppy disk, if you do not insert the floppy disk, click OK, the system will not give you the release.

Insert a password floppy disk and enter a different password for each account. At the same time, if you prefer, the key file in the password floppy disk can be copied to other floppy disks.

Third, remove the high security requirements of the password floppy disk

If one day, your security requirements for the operating system is not so high, and you are tired of every time you enter the system Insert a floppy disk, what should I do? Select “Save the startup password on this machine  You can, of course, you must have a floppy disk with the key stored in this step. This requires the authorization password to be entered when the password floppy disk is created. A reason.

If you are interested in the key file in the generated password floppy disk, you can further study the file in the floppy disk.

This function is secretive. I believe that everyone should not find him. Now let him see the sky again. After you see it, you should make good use of it. Don't let this tutorial go.
