How To Change SID On Windows 7 And Windows Server 2008 R2 Using Sysprep

Sysprep on Windows Server 2008 R2 Datacenter edition, but same steps apply for Windows7 also.

First, click to Start->Run, type sysprep and press OK.



This will open sysprep folder which is located in c:\Windows\System32. Open sysprep application.



This will open System Preparation Tool 3.14 window. As a System Cleanup Action select Enter System Out-of-Box Experience (OOBE). Important: select Generalize if you want to change SID, it�s not selected by default. As Shutdown Options select Reboot.



It will take some time for sysprep to finish, so grab a cup of coffee and wait.



After rebooting you�ll have to enter some data, for example, Country or region, Time and currency and Keyboard input.



Also, you�ll have to accept EULA. And that�s it. After booting, in Server Manager you�ll see that everything is changed, if you had some settings set now they�re changed.



Now you can again use PsGetSid to check that your OS has new SID.
