A utility tool designed to resolve Tailscale TPM (Trusted Platform Module) recognition errors on Windows and Linux systems.

This tool helps fix issues that occur when Tailscale's TPM-bound state becomes invalid or inaccessible. These problems typically arise after hardware changes or TPM key management operations, preventing Tailscale from functioning properly.

Use this tool if you encounter TPM-related errors with Tailscale after:

• Replacing your CPU or motherboard
• Performing TPM key management operations
• Resetting or clearing your TPM
• Any scenario where TPM keys have been changed or reset

The tool works by removing Tailscale's TPM-bound state files, allowing you to re-register your device with a fresh configuration.

Download the latest pre-built binaries from the GitHub releases page Github release.

Administrator privileges are required to run this tool. The application needs elevated permissions to:

• Stop running Tailscale processes
• Remove system-level configuration files

Run the executable as Administrator (right-click and select "Run as administrator").

Run with sudo:

sudo ./tailscale-tpm-fixer (TTF)

1. Close any Tailscale applications if they are running
2. Run the tool with administrator privileges
3. Review the list of files that will be removed
4. Press Y to proceed or N to cancel
5. After completion, re-register your device with Tailscale

The tool will automatically:

• Stop all running Tailscale processes
• Remove TPM-bound state files
• Provide confirmation when the operation is complete

• C:\ProgramData\Tailscale
• C:\Users\%USERNAME%\AppData\Local\Tailscale

• /var/lib/tailscale/tailscaled.state

Once the tool completes successfully, you'll need to re-register your device with Tailscale to reactivate it. Your device will be treated as a new node on your network.

For more information about Tailscale's secure node state storage, see the official documentation.
