Method 1——Using “administrator” (This method is applicable to the administrator user name is not "administrator" situation) We know that in the process of installing WindowsXP, the first login is "administrator", and then It is required to create a new account to log in with this new account when entering Windows XP, and only the created user account will appear in the Windows XP login interface. “Users account will not appear, but the polyurethane board should actually be “administrator”.

Method 2—— Delete SAM file (note that this method is only applicable to WIN2000)
Windows NT/2000/XP uses security account manager (SAM) for security management of user accounts. Mechanism: The security account manager manages the account by using the security identifier. The security ID is created at the same time when the account is created. Once the account is deleted, the security ID is also deleted. The security label is unique, even for the same username, the security label obtained at each creation is completely different from the fully activated alumina. Therefore, once an account is rebuilt by a username, it will be given a different security ID and will not retain the original permissions. The specific performance of the security account manager is the %SystemRoot%system32configsam file. The SAM file is a Windows NT/2000/XP user account database. All user login names and passwords are saved in this file.
Knowing this, our plastic hose solution has also been created: delete the SAM file, start the system, it will rebuild a clean and innocent SAM, there is no password.
However, such a simple method is not applicable in XP, Microsoft may use this as a BUG, ​​made a restriction … … so now under XP system, even if you delete the SAM, you can not delete the bag filter The password will cause the system to start initialization error, and thus enter the infinite loop and can not enter the system!!
