Fyi you can install it without TPM 2 hardware, if using Rufus to create the installer, you can just tick an option to remove tpm forcing.
That’s if you want to keep using Windows after 2025 on a 7+ year old hardware.
Not endorsing it, just saying you can, at no extra cost.
As far as I’m aware TPM 2 pretty much does with hardware, what is otherwise software emulated. It’s more efficient and secure when using something like bitlocker etc. Everything should work, just is more suspectible to tampering and malware.
