 By default changes (including proxy settings, passwords, bookmarks, installed software and malware) made in a VM are saved when it is shut down, but the .vmx configuration file can easily be edited to autorevert on shutdown, so that all changes are discarded.VMware Player is also supplied with the VMware Workstation distribution, for use in installations where not all client users are licensed to use the full VMware Workstation.In an environment where some machines without VMware Workstation licences run VMware Player, a virtual machine created by Workstation can be distributed to computers running Player without paying for additional Workstation licenses if not used commercially.
