WINXP/2K little-Known security command _ Web surfing

In Windows XP and Windows 2000 systems, there is a command that I am not generally familiar with, but powerful, that is: Syskey command.

This command can effectively enhance your system security. Perhaps you would say that it is not safe to enter your account and password when you enter Windows XP or Windows 2000? The famous Win 2000 input Method vulnerability you should have heard, if your computer is more than one person to use, other people can completely through the user to break the simple password to enter the system, exploit various vulnerabilities to gain administrator privileges. With the encrypted floppy disk made by SYSKEY, you can use 2000 and XP completely with ease. Let's look at the use of the SYSKEY command.

　　 the setting of double password protection

1. In the Start menu "Run" enter "Syskey", click OK.

2. This interface refers to the account database is the principle of NTFS encryption, for our general users, do not need to study the principle, we will use as long as good. Next click on "Update".

3. Here we select the password to start, enter a password, and then click OK. Doing so will enable WinXP to enter a password more than once during startup, playing 2 times as a cryptographic function. The operating system starts at the usual time before we enter the username and password will appear window prompts "This computer requires a password to start, please enter a startup password." This is the first password protection we have just created.

　　 second, the production of password floppy disk

1. If we choose "Save startup Password on floppy disk", this will generate a password floppy disk, without this floppy disk, No one wants to get into your operating system. Of course, if you have previously set the SYSKEY system startup password, here will also require you to enter the password again, to obtain the appropriate authorization, which is somewhat similar to our QQ password changes, we must know the original password.

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

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

Insert password floppy disk, according to different accounts, enter a different password. At the same time, if you want, the key file in the password floppy disk can be copied to another floppy disk.

　　 third, the removal of password floppy disk high security requirements

If one day, your operating system security requirements are not so high, and you are tired of every access to the system need to insert a floppy disk, how to do? Select "Save startup password on this computer", of course, this step you must have a floppy disk with a key, this and password floppy disk when required to enter the authorization password is a truth.

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

Simple and effective encryption method, quickly try it!
