PowerShell: Check Number of Logical Processors
Need to check how many logical processors (threads) a CPU exposes to Windows - for performance planning, licensing checks, or understanding multi-threading capacity? This one-liner pulls it straight from the system.
Prerequisites:
- Privileges: None
- Module: Built-in, no import needed
Quick Command:
Get-CimInstance -ClassName Win32_Processor | Select-Object Name, NumberOfLogicalProcessorsExample Output:
Name NumberOfLogicalProcessors
---- -------------------------
Intel(R) Core(TM) i5-14500T 20📦

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.
- NumberOfLogicalProcessors returns the number of logical processors (threads) the CPU exposes to Windows - this is often higher than the physical core count, since technologies like hyper-threading let each physical core handle more than one thread at a time.
