We all know and familiar with sysprep - System Preparation executable file
Sysprep Executable :-
Sysprep.exe is the main program that calls other executable files that prepare the Windows installation. Sysprep.exe is located in the %WINDIR%\system32\sysprep directory on all installations. Sysprep must always be run from the %WINDIR%\system32\sysprep directory and must run on the version of Windows with which it was installed.
Above is the little Information of sysprep, which you can use in VMware, when cloning VMs
Why do we require sysprep While cloning VMs:-
1. You can set Computer Name
2. You can set Administrator password, for post installation task
3. SID is created separately, Because in VM cloning, it does take the same SID, which in future conflicts with the original VM
Long story in short :- It allows you for custom installation, where you can specify IP address & other required details of system, as per your choice.
