How It Works:
- Get-CimInstance -ClassName Win32_BaseBoard queries the baseboard (motherboard) class - not to be confused with Win32_BIOS, which reports on the firmware rather than the physical board itself.
- SerialNumber returns the manufacturer's serial number burned into the motherboard - useful for asset tracking or RMA/warranty lookups.
Pro Tip:
On virtual machines, this often comes back empty, since there's no physical motherboard with a manufacturer-assigned serial number.
