There are two options for customizing instant clone virtual machines: VMware ClonePrep or Microsoft Sysprep.
- Creates a new computer account in Active Directory for each desktop.
- Gives the instant clone desktop a new name.
- Joins the desktop to the appropriate domain.
Sysprep is a Microsoft tool to deploy the configured operation system installation from a base image. The desktop can then be customized based on an answer script. Sysprep can modify a larger number of configurable parameters than ClonePrep, but ClonePrep is significantly faster. Majority of instant clone customers choose ClonePrep
