The point isn’t to store keys in the TPM. The point is to ensure you’re running an unmolested version of Windows that will enforce whatever security controls the DRM maker wants to have.
Part of that is things like:
* Don’t load an unsigned (or wrongly-signed) GPU driver, because it might be modified to allow a user to read from framebuffer memory after content has been decrypted.

- labcomputer 3y agoOh, no argument from me there, I’m just pointing out that you kinda need TPM to make your DRM not trivially bypassable. I imagine that the MPAA et. al. are planning to attack the splitter thingy one day, so they’ll want to make sure you can’t slurp the frame buffer when that avenue is gone.
