• In Windows XP we could change the SID with a tool called “newsid“
• In Windows 7 and also in Windows Server 2008 R2 “newsid” won’t work anymore!
• Changing the sid in Windows 7 we can perform just like the change of the sid in Windows Server 2008 R2

Let’ s try SYSPREP again!

1. First we take a look at the current SID with “psgetsid“. You can see the name of the machine and the current computer-SID
2. Now press “Windows button + R” (run)
3. Type in “%windir%\system32\sysprep\sysprep.exe“
4. Choose Enter System Out-of-Box Experience (OOBE) and Generalize (Verallgemeinern)
5. It will take some time for sysprep to finish, so grab a cup of coffee and wait
6. After the reboot the system is going to change some systemproperties until the following screens will appear. Adjust the settings and finish the sysprep…
7. After that we take a look at the SID for a second time…Oh look, there’ s another one – perfect
