Its just more garbage DRM. Its Sony telling you that you don't own your PS3 all over again except it's the PC you built and Microsoft telling you what you can and can't do with it. Try to crack your CPU key to fake the TPM and Microsoft will sue you out of existance just like Sony did with Geohotz. Thanks to the DMCA and it's anti-circumvention laws, we no longer own any hardware, we're just borrowing it.
