Man, even checking their official website makes me want to pull my hair out. Nowhere do they concretely mention either TPM or after some research what should be called TPP for intel. I can only guess that maybe they hide it behind yet another name (maybe Intel® Trusted Execution Technology ?) but the information on this is basically impossible to find on the internet at this point.

On the other hand, 4 more years is a lot, and they'll probably continue to release security updates for a year or two past 10's EOL (like they have with Windows 7).

Uh... can you tell me eli5 what does TPM do that w11 needs it so bad? It it for DRM ?

Yes. It's to ensure Microsoft always have full control over the code running on your device, so eventually Microsoft can require all Windows apps to come from its store, and you won't be able to do anything about it; because the hardware TPM module will reject any attempts to modify it.

you mean in the same vein as the huge epic apple trial? nah. sideloading and app installing will be allowed due to fear of government action. the tpm can ensure system files are not malware infected tho
