What is tpm.sys?

The file version detailed information of tpm.sys is TPM Device Driver. TPM is short for trusted Platform Module. This kind of module is a chip on an endpoint device and is specialized to store RSA encryption keys that are specific to the host system for hardware authentication under an international standard for a secure cryptoprocessor. TPM chip respectively includes an RSA key pair referred as the Endorsement Key (EK). The RSA key pair is preserved within the chip and cannot be read by software.

Depending on a special microprocessor, tpm.sys is able to safeguard hardware by integrating cryptographic keys into devices. Since TPM technical specification was compiled by a computer industry consortium called Trusted Computing Group (TCG), the specification of tpm.sys conforms to International Organization for Standardization (ISO) and International E as ISO/IEC 11889. Trusted Computing Group never stops improving the TPM specification. They have released revision 116 of the TPM specification version 1.2, and the TPM specification version 2.0 is being drafted and reviewed.

At the moment you possess ownership of the system, the Storage Root Key (SRK) is generated. This pair of keys is created by the TPM according to the Endorsement Key and an owner-designated password. A second key, named as an Attestation Identity Key (AIK) keeps the device from unauthorized firmware and software changes before they are implemented. When your computer needs to link to the network, the hashes are sent to a server that verifies that they match expected values. If any of the hashed components has been changed since last started, the match will fail, and the computer can not be given entry to the network.

Via tpm.sys, TPM chips can be applied into any major operating system and are in perfect conditions under the support of other security technologies. The chip enables secure boot by means of platform integrity measurements, intellectual property protection, authentication, and secure communications. Key Features of tpm.sys includes turnkey solution, full TCG compliance, hardware security, high performance, energy savings, software support, two interfaces. TPM is sometimes referred to the set of specifications applicable to TPM chips.

What are common signs of tpm.sys errors?

  1. "Compatible TPM cannot be found." when trying to enable bitlocker: You couldn't make any sense of the explanatory material regarding the TPM.
  2. TPM shows yellow exclamation mark in device manager. USB devices like printer and headset not working: Saying the "the device needs trouble-shooting",
  3. Error - Compatible Trusted Platform Module (TPM) cannot be found on this computer. Verify that this computer has 1.2 TPM and it is turned on in the BIOS.
  4. When you configure BitLocker on my Surface Pro, it said "A compatible TPM Security Device must be present on this computer, but a TPM was not found."
  5. Creating a USB Startup Key Only for a drive without a TPM: It seems simple enough yet you have sourced the entire network only to be referred to links that are outdated.
  6. A dialogue box that says ‘No TPM chip is detected'. You must reboot, enter into your computer's BIOS setup, and enable the TPM... etc..." Not sure what this is asking about.
  7. ERROR: An error occurred while checking if the TPM Storage Root Key (SRK) has a compatible authorization value. (code 0x80280803).
  8. Splash screen hangs, get No TPM or TPM has problem message, and netbios.sys file corrupted.
  9. When trying to turn Bit Locker on for the drive, you receive the following error: "A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found."

Why do I have tpm.sys errors?

The tpm.sys error often goes together with the new application of windows 7 ultimate edition: the BitLocker. BitLocker needs TPM for normal operation. When your system fails to connect to the TPM (security device), it is likely that anti virus or firewall software is blocking the connection. A corrupt or disabled drive could cause this problem.

After turning on the TPM feature in the BIOS, saving and exiting the configuration setup, rebooting your pc, Windows 7 automatically installed tpm.sys driver, but there is a Yellow exclamation point on the icon of this file. You are unable to turn on BitLocker. When going into the resources there is a conflict with some motherboard device.

In the course of trying to restore an image of your drive C by means of Macrium Reflect, drive C is locked and Macrium doesn't find the drive, only the backup USB drive so that you can select the image for the restore but can't select where to put that image. You cannot use bit locker and the drive is not encrypted.

How to fix tpm.sys errors?

Firstly, run Windows Memory Diagnostics and make sure that hard drive has no issues either. Also try to run CHKDSK to get the result of both the drive C and drive Dare clean. A configuration modification is required to enable, the TPM. This action will clear and turn on your TPM, but be aware that this request will delete any keys contained in the TPM. You can disable the firewall and the security chip in BIOS, then turn off the TPM service to see that the problem is fixed.

Guarantee that the USB drive is installed and available, and enable USB startup in BIOS and ensure that failure to find operating system won't appear. When starting Bitlocker, the TPM is displayed with the option to use USB. You can get detailed instructions from Technet on taking ownership of your TPM module. It will meet your requirement for initializing TPM as per the instructions. If TPM behaves badly then just disable it and follow these online instructions on how to enable Bitlocker without the need for TPM by means of an USB thumb drive to decrypt the computer on startup.

For the final and easy to operate method, it is suggested to run DLL TOOL to scan your system thoroughly for any other corrupted dll files and registry entries, and have them fixed automatically.
