Interesting… I didn’t realise Skylake isn’t supported. I agree with your comment. I thought people were talking about much older equipment.
TPM 2 has been around since 2015ish and I wouldn’t be surprised if Windows starts relying on it more heavily. A lot of businesses have already required employees to use computers with TPM 2.0 for a long time, and enterprise use is a big focus for Microsoft.
User agents were commonly used for the wrong reasons - fingerprinting, sites that block particular browsers rather than using proper feature detection, etc. so I’m glad to see them slowly going away.
