Hello Thank you for your question and reaching out. I can understand you are having query\issues related to Security Processor Attestation. Device Health Attestation is utilised in a professional setting; it is not necessary or utilised on a personal computer. Your BIOS must support TPM and Secure Boot and be in UEFI Mode in order for that feature to function. Device Health Attestation is a means for a PC to inform a System Administrator about the security hardware on the PC; it does not boost security. The Microsoft documentation on Device Health Attestation is provided below; it is a process used by System Administrators to ensure that all of their PCs fulfil their standards using a management console; it is not a method utilised by home users.

Check your motherboard manual to ensure that it supports TPM 2.0. Ensure that your BIOS is up-to-date. Check your Windows 11 settings to ensure that the TPM is enabled. You can do this by going to the Settings app, clicking on "Update & Security", and then clicking on "Device security". From there, you can check if TPM is enabled and if it is functioning correctly.
