Windows Defender vulnerable driver warning: updating LibreHardwareMonitorLib.dll breaks HardwareMonitor plugin (missing deps) — fix script

What’s happening

Windows Defender may block/flag the old bundled LibreHardwareMonitorLib.dll (vulnerable driver / vulnerable driver blocklist).
So some users replace LibreHardwareMonitorLib.dll in the TrafficMonitor install folder with a newer one.

After that, TrafficMonitor can crash on startup or the HardwareMonitor plugin fails to load with errors like:

• System.Memory ... could not be found
• DiskInfoToolkit ... could not be found

Reason: newer LibreHardwareMonitorLib.dll versions reference additional managed dependencies that are not shipped with TrafficMonitor by default.

Fix / Workaround

I made a small helper script that:

1. inspects which assemblies LibreHardwareMonitorLib.dll references
2. downloads the matching dependencies from NuGet
3. copies them into the TrafficMonitor install folder
4. adds binding redirects to TrafficMonitor.exe.config if needed

How to use

1. Update LibreHardwareMonitorLib.dll (place it next to TrafficMonitor.exe)
2. Run (Admin may be required if installed under Program Files):

powershell -NoProfile -ExecutionPolicy Bypass -File .\deploy_tm_deps.ps1 -TrafficMonitorDir "C:\Path\To\TrafficMonitor"
