https://community.intel.com/t5/Software-Archive/TXT-error-code-0xC0001041/m-p/1093506#M66115 Hello, I was tried setup TXT and always got TXT.ERRORCODE: 0xC0001041 and reboot after TBOOT: executing GETSEC[SENTER]... I decoded this as Class=4, Major=4, Minor=0. The description for this error is "TPM NV is unlocked".
