Windows system sid modification method

First, the meaning of Sid

Sid is called security identity, that is, network security label. It is used to uniquely identify information such as computer accounts, user groups, and user accounts. He is determined by the computer parameter, the current time, and the sum of the CPU time spent by the current user state thread to ensure its uniqueness. Many system software uses this flag to uniquely identify a user.

Second, check the local sid

1) cmd into the command line, enter who am i /all. You can view the sid information of the currently logged in user

2)Regedit Enter the registry and enter HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion \\ProfileList with sid on the left and ProfileImagePath on the right to view the username corresponding to the sid.

Three, modify sid

Cloning the system on virtual, or using the ghost image to install the system will encounter the same problem with sid. In this case:

If it is win2003 or win xp system, you can extract the syspre.exe and factory.exe files in DEPLOY.CAB under the support\\tools\\ file of the installation package. Then run syspre.exe and choose to re-encapsulate.

If it is a win7 system, you can run syspre.exe in the path C:\\Windows\\System32\\sysprep. Choose to repackage.
