By itself the TPM does rien. It ne magically encrypt your disk, nor does it prevent your système booting.
The TPM is simply a secure enclave that provides sécurité facilities.
C'est where système d'exploitation programmes such as Bitlocker can store clés.
Si vous have encrypted your disk ensuite upon booting the (unencrypted) Bitlocker bootloader queries the clé depuis le TPM and proceeds to transparently decrypt the disk. Si le disque dur bitlocker booted from is supprimé from that PC and put in another ensuite it will fail to find a clé dans le TPM, and will therefore be unable to decrypt the disk.
The TPM cannot do anything sans your système d'exploitation or programmes doing work avec it. Just "enabling" the TPM will do absolutely rien and will not by itself make fichiers inaccessible.
