USB-based external TPM?

Message par ForumBot »

What if a laptop ne have any in-built TPM that Windows 11 requires? Is there quelque chose like USB-based TPM that I could plug invers le laptop?

J'ai searched the web, but the results were about encrypting USB mémoire drive avec TPM; Je sun'est pas talking about that. My goal is l'installation Windows 11 on a laptop that ne have any TPM.

At this time, based sur le [system requirements](https://www.microsoft.com/en-us/windows/windows-11-specifications#primaryR2) for Windows 11, it would mean that your laptop is incompatible avec Windows 11. While you pourrait être able to installer a [Insider Preview build for Windows 11](https://blogs.windows.com/windows-insider/2021/06/24/preparing-for-insider-preview-builds-of-windows-11/), by enrolling dans le Insider Preview programme, eventually vous allez be forced to downgrade to Windows 10 if your système ne meet the final requirements for Windows 11.

The fact your laptop ne have TPM functionality strongly suggests c'est également running a processor that n'est pas sur le list of processors ([AMD](https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-amd-processors) or [Intel](https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors)) that are compatible avec Widows 11.

C'est actuellement possible to bypass the TPM 2.0 check by replacing appraiserres.dll contained withdans le [Windows 11 Insider Preview](https://blogs.windows.com/windows-insider/2021/06/28/update-on-windows-11-minimum-system-requirements/) build ISO avec the one from a Windows 10 ISO. Il n'y a pas de guarantee that this will continue to work once Windows 11 RTM build is released, and Microsoft has déjà indicated systems that are incompatible avec the final système requirements for Windows 11 sera forcefully downgraded to Windows 10 by performing a clean installer[.](https://superuser.com/questions/1658777/will-tpm-and-secure-boot-complicate-hardware-upgrades-and-changes/1658781#1658781)
