A lot of Windows systems ship without a TPM 2.0 module. Intel Macs, older desktops, custom builds with it disabled in BIOS, and VMs that do not pass through the host TPM all hit the same wall. Without TPM 2.0, Windows blocks a growing list of features that depend on platform security.

What breaks without TPM 2.0

  • Windows 11 will not install or upgrade cleanly.
  • BitLocker cannot create a TPM protector.
  • Windows Hello PIN and biometric login are unavailable.
  • Credential Guard and Core Isolation will not activate.

The fix

FlexTPM adds a fully functional TPM 2.0 device to Windows. After installation, Windows and applications see a standard Trusted Platform Module.

Installation

After reboot, Windows provisions FlexTPM through the standard TPM stack. FlexTPM maintains the consistent TPM and security state required for modern Windows validation and attestation workflows.

  1. Purchase a license at flextpm.com/pricing.
  2. Download the installer with your key at flextpm.com/downloads.
  3. Run the installer.
  4. Reboot once.

Verifying it works

Option 1: Press Win + R, type tpm.msc, and hit Enter. TPM Management should show that the TPM is ready for use.

Option 2: Open Security processor details in Windows Security. It should list TPM 2.0 and Attestation as ready.

Option 3: If the link does not open, open Windows Security, go to Device Security, and select Security processor details.

What works

  • Windows 11 upgrade checks pass.
  • BitLocker encryption can use a TPM protector.
  • Windows Hello PIN login works, with biometric support when the hardware supports it.
  • Credential Guard and Core Isolation can be enabled.
  • Windows Security reports the TPM and attestation state.

Supported systems

FlexTPM is built for x86-64 Windows systems without a working hardware TPM 2.0, including Intel Macs running Windows, older PCs, custom desktops, and virtual machines without TPM passthrough.

Apple Silicon Macs are not compatible because they do not support Boot Camp Windows.
