Having a TPM module plugged into a motherboard is the old way. They're all scalped so anyone needing this is sol.
The new way is to enable a feature of your CPU. (CPUs from last 5 years)
This can be done in the BIOS. It's in a different place depending on motherboard manufacturer, so hard to give instructions.
For AMD it's called fTPM. For Intel it's called PTT.
Some people enable it then the PC Health Check app says Win 11 is supported.
Some people enable it then the PC Health Check app says Win 11 NOT supported.
Some people enable it and it works initially, then a bit later on it doesn't work anymore.

OK, cheers.

So we don't actually need a physical TPM then?

With a 5800x it was easy to enable AMD fTPM and it now passes the W11 check.

With my older 6700K which has PTT - hard to find in the BIOS under firmware TPM - but although this shows as a TPM 2.0 device it still didnt pass W11 checks - it looks like 6700K and even some newer generation Intel CPUs simply arent supported - quite shocking really.
 
AMD have said you can enable fTPM in the BIOS with Ryzen CPUs:

However,the problem with fTPM,any reason which leads to your BIOS being reset,etc like memory tweaking,overclocking or updating a BIOS,will cause issues,and you will need to revalidate stuff. People will need to remember the keys - how is that going to work for most people??

Apparently Win11 PRO can disable Bitlocker so there might be an avenue out of fTPM getting in the way.

A bigger issue though is secure boot - how is that going to work if you dual boot??
 
The focus is going to be on TPM but the supported processor list is even more stringent - processors from 2015/2016 support firmware TPM and that appears OK in Windows but then stilll fail the W11 requirements check.

What when you flash the BIOS with a new version when using fTPM?

Even if the TPM issues is easily sorted by module or BIOS setting the processor requirement is going to catch a lot of people out - for Intel https://docs.microsoft.com/en-us/wi...pported/windows-11-supported-intel-processors - 7700K and earlier look like theyre out of luck

My Dell Latitude E5470 has a TPM2.0 module,but can't run Windows 11?? What a joke!!

Yes - the issue is that if the BIOS gets reset,surely it will reset any the validation data in the BIOS which is used to confirmed what Windows is holding??

But if Win11 PRO can switch off Bitlocker it might be a way out of it.
 
Hang on a min.

I don't think things are as bad as they seem. Here you can see a hard and soft floor:

There are new minimum hardware requirements for Windows 11. In order to run Windows 11, devices must meet the following specifications. Devices that do not meet the hard floor cannot be upgraded to Windows 11, and devices that meet the soft floor will receive a notification that upgrade is not advised.

Hard Floor:

  • CPU: Core >= 2 and Speed >= 1 GHz
  • System Memory: TotalPhysicalRam >= 4 GB
  • Storage: 64 GB
  • Security: TPM Version >= 1.2 and SecureBootCapable = True
  • Smode: Smode is false, or Smode is true and C_ossku in (0x65, 0x64, 0x63, 0x6D, 0x6F, 0x73, 0x74, 0x71)
Soft Floor:

  • Security: TPMVersion >= 2.0
  • CPU Generation
So as long as you meet the Hard Floor windows 11 will be installable.
