TPMs have been widely deployed for around a decade. Widevine doesn't use them - it makes use of the protected video path hardware built into the GPU or motherboard chipset.
- immibis 3y agoAs far as I know they only became mandatory with Windows 11, so give them a few years to become universal.
- mjg59 3y agoWindows 11 was the first release to enforce anything at the OS level, but Windows client sticker certification has required them since 8.1, released in 2013. As a result almost all Windows client systems in the wild have some form of TPM by default (in most cases running on the ME or the PSP)
- Mindwipe 3y agoIndeed, more systems than have the existing PlayReady 3000 GPU mechanisms. But services still use that rather than a TPM, because a TPM is useless.
