How It Works:
- Get-CimInstance -ClassName Win32_Processor queries the processor class, which reports details about each physical CPU installed in the system.
- Name shows the exact processor model as reported by the manufacturer.
- NumberOfCores returns the number of physical cores on that processor - not to be confused with logical processors (threads), which can be higher if the CPU supports hyper-threading.
