How It Works:
- Get-CimInstance -ClassName Win32_ComputerSystemProduct queries a class that holds product-level identification info about the machine.
- UUID returns a unique identifier (Universally Unique Identifier) assigned to the system - typically burned into the motherboard/firmware at manufacture time, and used by things like asset management tools, virtualization platforms, and some licensing systems to uniquely identify a specific machine.
Pro Tip:
Unlike serial numbers, the UUID format is consistent across manufacturers and virtual machines alike, making it a more reliable identifier when working across mixed physical/virtual environments.
