Four general types of maintenance philosophies can be identified, namely corrective, preventive, risk-based and condition-based maintenance.
Total Productive Maintenance
In case of physical access, computers with TPM are vulnerable to cold boot attacks as long as the system is on or can be booted without a passphrase from shutdown or hibernation, which is the default setup for Windows computers with BitLocker full disk encryption.
In any event: it is not advisable to disable it, this simply weakens the security of your system with no upside benefit.
Clearing the TPM can result in data loss. ... Clearing the TPM causes you to lose all created keys associated with the TPM, and data protected by those keys, such as a virtual smart card or a login PIN. Make sure that you have a backup and recovery method for any data that is protected or encrypted by the TPM.
In the BIOS, usually under the Security section, use the option to clear the TPM. This action cannot be reversed and will result in the loss of any encrypted data - for example, you will then need to reimage the machine and re-encrypt the drive.
The TPM is a cryptographic module that enhances computer security and privacy. Protecting data through encryption and decryption, protecting authentication credentials, and proving which software is running on a system are basic functionalities associated with computer security.
Procedure
To change to a new TPM owner password, in TPM. msc, click Change Owner Password, and follow the instructions. You will be prompted to provide the owner password file or to type the password. Then you can create a new password, either automatically or manually, and save the password in a file or as a printout.
Open the Device Manager and look for a node called “Security devices“. Expand it and see if it has a “Trusted Platform Module” listed. This will let you view the current status of the TPM chip: activated or enabled. If there is no TPM installed on your computer, you'll get the message “No Instance(s) Available“.
To Clear TPM: Boot computer using F2 into the BIOS setup mode. Locate the “Security” option on the left and expand. Locate the “TPM” option nested under the “Security” setting. To clear the TPM you must check the box saying: “Clear” to clear the TPM hard drive security encryption.
You cannot physically remove the TPM. It is soldered to the motherboard.
TPM (Trusted Platform Module) is a computer chip (microcontroller) that can securely store artifacts used to authenticate the platform (your PC or laptop). TPM (Trusted Platform Module) is a computer chip (microcontroller) that can securely store artifacts used to authenticate the platform (your PC or laptop).
Clearing the TPM (Trusted Platform Module) resets the TPM to an unowned state. It's something you would do if you were selling your laptop to another person, so the answer is no, you do not need to clear the TPM.
Trusted Platform Module
Each TPM has a master wrapping key, called the storage root key, which is stored within the TPM itself. The private portion of a storage root key or endorsement key that is created in a TPM is never exposed to any other component, software, process, or user.
Warning: clearing the TPM erases information stored on the TPM. You will lose all created keys and access to data encrypted by these keys.
1 Product overview. The HP Trusted Platform Module Accessory (TPM) provides secure device identity with certificate private keys generated and protected by the TPM. The TPM strengthens protection of encrypted credentials and data stored on the printer or MFP by automatically sealing device encryption keys to the TPM.
To open it, press Windows+R to open a run dialog window. Type tpm. msc into it and press Enter to launch the tool. If you see information about the TPM in the PC—including a message at the bottom right corner of the window informing you which TPM specification version your chip supports—your PC does have a TPM.
PPI stands for Physical Presence Interface. For your reference:https://trustedcomputinggroup.org/resource/tcg-physical-presence-interface-specification/ Please Note: Since the websites are not hosted by Microsoft, the links may change without notice.
TPM PPI Deprovision Override (ENABLE) Description: These options make it so the user isn't prompted to make changes to TPM/Encryption related configuration.
How to reset and clear the TPM Chip
Resolution
It is possible to use BitLocker without TPM, though the option needs to be enabled first. In that case, clearing the TPM will not make a difference. However, it looks like you are using BitLocker with TMP, so this does not apply in your case. Turning off, disabling, deactivating, or clearing the TPM.
Steps to Disable PTT in the BIOS to Enable TPM Security:
Trusted Platform Module, or TPM, is a security device that holds computer-generated keys for encryption. It is a hardware-based solution that prevents hacking attempts to capture passwords, encryption keys, and other sensitive data.
