This build uses a preliminary version of the Secure Boot Policy, although the on-disk structure is identical to later builds: | This build uses a preliminary version of the Secure Boot Policy, although the on-disk structure is identical to later builds: | ||
* Signature validation is different: the policy must have a hash in or be signed by a certificate in the UEFI Key Exchange Key signature database. | * Signature validation is different: the policy must have a hash in or be signed by a certificate in the UEFI Key Exchange Key signature database. | ||
* The CanUpdate element is used here; the code using it was removed later but the element remained in the file format. A path to an updated policy can either be set in a UEFI variable; alternatively, for BitLocker where the VMK is sealed by the TPM, an updated policy is read from osdevice:\LatestPolicy.p7b. This policy must have a valid signature. | * The <code>CanUpdate</code> element is used here; the code using it was removed later but the element remained in the file format.

* The updated policy must have a PolicyPublisher equal to one of the CanUpdate GUIDs in the loaded policy; also, the policy version must be greater than the loaded policy's version. If all conditions pass, the updated policy is installed to UEFI non-volatile storage and used as the active policy. | * The updated policy must have a <code>PolicyPublisher</code> equal to one of the <code>CanUpdate</code> GUIDs in the loaded policy; also, the policy version must be greater than the loaded policy's version.

* BCD rules are identical to later builds; that is, BCD elements can be overridden by the policy to either be forcibly ignored, or for deletion to be disallowed from the running OS, or for the element value to be locked to a value or one of several values listed in the policy. | * BCD rules are identical to later builds; that is, BCD elements can be overridden by the policy to either be forcibly ignored, or for deletion to be disallowed from the running OS, or for the element value to be locked to a value or one of several values listed in the policy. | ||
* Registry rules are not used for low-level cryptographic settings as in later builds but instead are used to override registry values anywhere in HKLM\SYSTEM. The operating system loader winload.e* and NT kernel both have code implementing this functionality; the former uses the policy to override the registry values it reads from that hive. | * Registry rules are not used for low-level cryptographic settings as in later builds but instead are used to override registry values anywhere in <code>HKLM\SYSTEM</code>.

* Option flag bits are completely different from later builds; only 3 bits are used, all by the operating system loader; bit 0 disables the Edit Options menu, bit 1 disables the Advanced Options menu, bit 2 is unknown but related to the Advanced Options menu. | * Option flag bits are completely different from later builds; only 3 bits are used, all by the operating system loader; bit 0 disables the Edit Options menu, bit 1 disables the Advanced Options menu, bit 2 is unknown but related to the Advanced Options menu. | ||
