Need to check who made the TPM chip and what firmware version it's running - for security auditing or firmware update checks? This one-liner pulls it straight from the system.

Prerequisites:

- Privileges: Run as Administrator
- Module: Built-in, no import needed

Quick Command:

```powershell
Get-CimInstance -Namespace "root/CIMV2/Security/MicrosoftTpm" -ClassName Win32_Tpm | Select-Object ManufacturerIdTxt, ManufacturerVersion
```

Example Output:

```powershell
ManufacturerIdTxt ManufacturerVersion
----------------- -------------------
PRLS              0.0.0.1
```

How It Works:

- Get-CimInstance queries the dedicated TPM namespace, same as the previous TPM checks.
- ManufacturerIdTxt returns a short code identifying the chip manufacturer - common values include IFX (Infineon), NTC (Nuvoton), or PRLS on Parallels virtual machines.
- ManufacturerVersion returns the firmware version running on that specific chip - useful for checking against known firmware vulnerabilities or update advisories.

Pro Tip:

On a virtual machine, ManufacturerIdTxt will show the virtualization platform instead of a real chip manufacturer - a quick way to confirm you're looking at a virtual/firmware TPM rather than dedicated hardware.
