Initializing the TPM chip 2

When you use the TPM function for the first time or you want to register the user again, you have to initialize the TPM chip.

•• Initializing the TPM chip erases all authentication information saved on the TPM chip. Any decision to initialize must be taken carefully.

•• To initialize the TPM chip again while the TPM function is in use, you have to decrypt any existing files and folders encrypted by the TPM function first. Otherwise, you will not be able to access the files and folders after re- initialization.
