Hi I have a Dell XPS desktop. The motherboard was changed and now I cant get TPM 2.0 so that means I cant update from win 10 to win 11. The bios is showing a TPM installed and enabled but its not the 2.0 HELP PLEASE

A few quick things to try before assuming the machine cannot do Windows 11, . Many XPS desktops use firmware TPM (Intel PTT on Intel CPUs, AMD fTPM on AMD) rather than a plug-in TPM chip. After a motherboard swap, BIOS can default to a discrete TPM 1.2 or simply disable PTT/fTPM. As noted, the exact XPS model matters, and if your system was Win11‑ready before, it is fair to ask the repair shop to supply a board/config that restores TPM 2.0.

Steps that usually fix this on Dell towers:

  • Update the BIOS to the latest version first.
  • In BIOS, under Security, look for TPM/TPM 2.0/Intel PTT (Intel) or AMD fTPM (AMD). Disable any Discrete TPM option, then enable PTT/fTPM. If there is a 1.2 vs 2.0 toggle, choose 2.0 and save.
  • If the BIOS asks to Clear/Activate the TPM, suspend BitLocker first (if used), or you can lock yourself out of encrypted data.
  • Some boards shipped with a TPM 1.2 module that cannot be upgraded to 2.0; in that case, using PTT/fTPM (if supported by the CPU/BIOS) is the path to TPM 2.0.

Verify in Windows:

  • Run tpm.msc and check Specification Version shows 2.0.
  • Or use one of these:
wmic /namespace:\\root\cimv2\security\microsofttpm path win32_tpm get SpecVersion,ManufacturerIdTxt
powershell -command "Get-Tpm | Select TpmPresent,TpmReady,ManufacturerIdTxt"

Windows 11 requires TPM 2.0, so you should see 2.0 once the right option is enabled or the right board is installed Windows 11 specifications. Microsoft’s guide has vendor-agnostic BIOS tips: . For Intel systems, PTT is the firmware TPM 2.0 implementation: Intel Platform Trust Technology. If you still only get 1.2 after these steps, the replacement board likely lacks TPM 2.0 support and should be swapped.

There are some hundred plus Dell XPS desktop models. However if you feel yours had TPM 2.0 before the repair then you call up the repair company and ask for them to fix it right.
Since the full model is missing here I can't check what TPM it might have.
