When Cloning VM to Template or to another VM.
Is this all done through VMware Wizard (One Stop Shop), or there is  preparation to do before cloning.
Also is the customization of sysprep mandatory (which I think so). If it is mandatory why it is an option on the wizard ?

Thank you

It's all done through the clone option, there is nothing further do you to do, unless you want to use the additional Customization Specification, which includes Sysprep and there is an option for this.

The option you are looking for is called

Select Generate New Security ID (SID) and click Next.

It's recommended by Microsoft to Sysprep ALL Windows OS, which are CLONED.

It can be, if you select Generate New Security ID (SID), otherwise it's not.

and it depends if you want or need to Sysprep. - Generate new SID

Unless if you are not planning to leave the original VM on the same network as the cloned one.
Otherwise you cannot have 2 VMs with the same system IDs

Actually that's a little incorrect! We were all DUPED and were led to believe that if you had two computers with the same SID on a network, the world was going to explode, this is not true.... and again, rather than take my response, I would ask you to experiment, and see what happens, if you have two computers with the same MACHINE SID (e.g. not sysprepped) in a DOMAIN or WORKGROUP, do they work ? - yes, cause issues, well that depends on what you do with them!

The MACHINE SID (which is what Sysprep changes, amongst other things) can exist on a network with other machines with the same MACHINE SID, and NOTHING bad happens!

Because, when you join a machine to a DOMAIN, it gets a DOMAIN SID, and that's what used! SYSPREP is not responsible for a DOMAIN SID....

I think you may need to have a read and research SIDs.

This was published many years ago, and shocked the world, if you've not read it...

The Machine SID Duplication Myth (and Why Sysprep Matters)

and even VMware states this...

Duplicate SIDs do not cause problems when the computers are part of a domain and only domain user accounts are used. However, if the computers are part of a Workgroup or local user accounts are used, duplicate SIDs can compromise file access controls. For more information, see the documentation for your Microsoft Windows operating system

If you want to discuss SIDs at length, I would suggest a new question, rather than continuing here, as this question is about CLONE function and Guest Customization Option.
