● password maximum lifetime of the strategy determines how long a password can be used, will expire after the password expires, the system will require users to change passwords. If set to 0, the password never expires. Under normal circumstances can be set to 30 to 60 days or so, a specific expiration time depends on your system, more stringent security requirements. Can be set up to 999 days.
● Minimum Password Age determines the strategy used to how long a password before it can be modified. Set to 0 to a password can be reused indefinitely, the maximum is 999. This strategy and the If the Therefore, if you want
● Minimum password length determines the strategy of the length of a password, valid values in between 0 and 14. If set to 0, then no password, which is the default value of the system, and from a security perspective, allowing the user without a password is very dangerous there.

If you have suffered hacking or other malicious damage, the system super user name will be immediately exposed, vandals targeted immediately to find the password. We also mentioned earlier, the absolute security of the password does not exist, therefore, for security reasons, you can get rid of the Administrator account name, and then almost no authority to create a false Administrator account. Specific methods as follows.
open the it plain to the Administrator to reset a user name. Then create a name for the Administrator of the restricted users to confuse intruders.
Note: Windows XP Home version of the MMC-based approach to security management a lot of restrictions, and the default Administrator user is hidden in the Administrator users will not be able to change the properties. The only solution is to enter safe mode, then the hidden Administrator user will appear in the user selection list, the default password is blank, how? Enough to risk it! With the Administrator user login,
