The Alps Winbond Trusted Platform Module 1 2 driver allows Windows to communicate with the computer’s TPM security hardware. Although listed under Audio, this device is a security component rather than a sound controller, so its driver will not resolve speaker or microphone problems.

Key Features

• TPM hardware communication: Provides the interface Windows needs to recognize and access the compatible Trusted Platform Module.
• Security feature support: Helps supported Windows security tools interact with hardware-backed key storage and platform integrity functions, depending on the computer’s configuration.
• Device identification: A matching driver can resolve a missing-driver warning for the TPM in Device Manager.
• System-specific compatibility: Driver selection depends on the hardware ID, Windows version, and system architecture—not just the Alps Electric vendor listing or device name.

How to Install

1. Confirm the device identity. Open Device Manager and locate the TPM, typically under Security devices or, if unidentified, Other devices. Open Properties > Details > Hardware Ids and compare the identifiers with those supported by the download.

1. Check Windows compatibility. Select a package explicitly intended for your version of Windows 11, 10, 8, or 7 and the correct architecture. A listing covering these systems does not guarantee that every driver package supports all four. TPM 1.2 also does not satisfy Windows 11’s standard TPM 2.0 requirement.

1. Prepare before making changes. Save your work and create a restore point if available. If device encryption or BitLocker is enabled, make sure you can access your recovery key. Do not clear the TPM as part of a routine driver installation.

1. Install the matching driver. Extract the downloaded archive if necessary, then run the supplied installer. If the package contains driver files without a setup program, choose Update driver in Device Manager, select Browse my computer for drivers, and point Windows to the extracted folder.

1. Restart and verify. Restart if prompted, then check Device Manager for warnings. You can also run `tpm.msc` to review the TPM’s reported status. If installation fails, use the computer manufacturer’s recommended package rather than forcing an incompatible driver.

Common Issues and Fixes

• Install fails or rolls back: Confirm the TPM is enabled in BIOS/UEFI and that no pending reboot exists. Run the Alps installer as administrator, temporarily disable security software, and check Device Manager for a failed “Trusted Platform Module” entry before retrying.
• Device not detected: In Device Manager, enable View > Show hidden devices and look under Security devices. Reseat the TPM header if applicable, verify BIOS has the discrete TPM/security device enabled, and ensure the Windows TPM service is running. An “Unknown device” may need the Alps Winbond TPM 1.2 package matched to its hardware ID.
• Driver version conflicts: Windows may load an inbox TPM driver over the Alps package. Uninstall the existing TPM driver, reboot, then install the Alps Winbond TPM 1.2 driver. Do not force a TPM 2.0 driver onto this 1.2 device; check the hardware ID first.
