Re: It really boils down to money.
TPM module really is not the issue. Despite all press claims. If your machine has a processor recent enough to make Microsoft's supported CPU list it has an embedded TPM 2.0 module. Now there are a small number of machines out there where the bios does not give the option to enable this but for most supported CPUs it is merely a matter of enabling the embedded module. Pre windows 11 the default was to disable this. There may also be a secure boot issue. While Windows 11 does not require secure boot to be enabled it does require it to be supported. This requires a pure UEFI boot. No compatibility support module. Again pre Windows 11 enabling the compatibility support module was the default to enable pre UEFI add in boards to work.
