Changing SID Server 2012

Question

Hello,
In Server 2008, to be able to create new VM using same (copied) VHD, we had to use SYSREP to change SID or 3rd party tools, if we wanted to join it to the same domain, otherwise we got an instability on servers.
How can we change/update SID in server 2012? I can't find SYSPREP nor other tool.
Or maybe we don't need to change SID anymore?
Thanks

I belive you don't need to, it's actually just a precaution...
Though, if you are using domains, you might need to opt the server out of the domain, and then join the domain again.
If you are also using it to connect to your own wsus server, you might need to run a registry script with this:
@echo off
Echo Save the batch file "AU_Clean_SID.cmd". This batch file will do the following:
Echo 1. Stop the wuauserv service
Echo 2. Delete the AccountDomainSid registry key (if it exists)
Echo 3. Delete the PingID registry key (if it exists)
Echo 4. Delete the SusClientId registry key (if it exists)
Pause
@echo on
net stop wuauserv
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v AccountDomainSid /f
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v PingID /f
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
Pause
net start wuauserv
Just save it as f.ex. Delkeys.reg
And then register it to get updates from wsus server again.
