How to Query TPM Level from a Batch File in Windows

In modern computing environments, Trusted Platform Module (TPM) technology plays a crucial role in ensuring system security by providing hardware-based security functions. Being able to determine the TPM level on a system is essential for various security-related tasks. Fortunately, you can query the TPM level directly from a batch file in Windows, allowing for convenient automation and scripting.

Step 1: Understand TPM Levels Before delving into the batch file commands, it's essential to understand the different TPM levels and their significance. TPM versions typically range from 1.2 to 2.0, with each version offering different security features and capabilities.

Step 2: Utilize Command-Line Tools Windows provides command-line tools that allow you to retrieve TPM information directly from a batch file. One such tool is tpmtool getdeviceinformation, which provides detailed TPM device information, including the version.

Step 3: Execute Command-Line Commands To query the TPM version from a batch file, you can use the tpmtool getdeviceinformation command. This command retrieves information about the TPM device, including the version, and displays it in the command prompt window.

Step 4: Alternative Command Option Additionally, you can use the wmic command-line utility to query TPM information. The command wmic /namespace:\\root\cimv2\security\microsofttpm path win32_tpm get SpecVersion,ManufacturerVersion retrieves both the SpecVersion and ManufacturerVersion of the TPM, providing comprehensive information about its capabilities.

Step 5: Implement Batch File Scripting Now that you have the necessary command-line tools and commands, you can create a batch file script to automate the process of querying the TPM level. Simply include the appropriate command within a batch file, and you can easily retrieve TPM information with a single click.
