Should just use Linux, tbh.
windows 11: doesn’t work without tpm 2.0
(some) linux distro: doesn’t work if tpm 2.0 enabled
You can get windows 11 working on non tpm 2.0 systems. It’s a soft requirement that Microsoft enforces with the stock installer but can be bypasses.
You can, but MS disables automatic updates without telling you. I have TPM but my CPU is one generation too old apparently, so they silently disabled updates on my machine and I didn’t realise I was still on 21H2 until a couple of weeks ago and had to manually update it.
The manual update worked and it didn’t warn me about anything or encounter any issues, but that was a massive pain.
This is probably hardware-specific, but I installed void linux on my thinkpad x1 last week, and it can’t shutdown or wake up from sleep until I disabled tpm 2.0 from bios. Very weird. Other distros I tried so far didn’t have this problem.
Windows 11 does, just not by default. My HP elitedesk 800 G3 server doesn’t have TPM 2.0 and it’s running 11 fine and without a MS account.
