“For the past three years, Microsoft documented a way to run Windows 11 on PCs that lack Trusted Platform Module 2.0 hardware – but that workaround has now disappeared from its help page.”
Microsoft documented a TPM 2.0 workaround for three years, then deleted it without a word. Defender started flagging Flyby11, a tool that does the same job. Microsoft now tells those users to roll back to Windows 10, which loses support this year. PC makers will happily sell the replacements.
