What is the term for a VM that writes unique information to the local hard disk after being initially provisioned?

Stateful

Explanation:

Virtualisation is a term in computer system, whereby a network card can be used to run multiple operating system on a virtual machines or VM.

Virtual machines are managed by hypervisors or hyper-V and provide containers to run separate OS activities. When the VM writes no unique information to the local hard disk, it is in a stateless mode, but when the written information is unique, it is stateful.
