Just completed a clean install of Windows 10 on my Precision M4500. All devices registered with Windows drivers or otherwise automatically installed (e.g. NVIDIA video driver). Exception: USH Broadcom and ST Free Fall drivers. Found both at these locations:
USH:

Free Fall Sensor:

I can report that the ControlVault and Dell Data Protection | Access components work as one would expect, even with the system's TPM (must be enabled in BIOS).
This is the first time I've had the system fully operational since it was purchased with Windows 7!
Please do not ask for any further details or techniques. I only found this by trial and error. I think I just got lucky!
