PowerShell: Get TPM Manufacturer and Firmware Version
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:
Get-CimInstance -Namespace "root/CIMV2/Security/MicrosoftTpm" -ClassName Win32_Tpm | Select-Object ManufacturerIdTxt, ManufacturerVersionExample Output:

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.
