2.7.1.3 Update Content Corrupted

This failure scenario occurs when the installation files that are associated with an update are corrupted or modified either due to unintentional causes, such as network unreliability, or an intentional attempt to breach security.

As a safeguard, it is recommended that the client accept content only for an update that is signed by a trusted certificate and whose hash matches the value retrieved from the update metadata, as specified in [MS-WUSP] section 5. These cryptographic techniques ensure that the client can detect corrupted content in all cases.

It is recommended that the client delete the suspect files and not attempt installation if corruption is detected during the recovery steps.

Because no change is made to the client environment, when corrupted content is encountered, there are no negative consequences from recovery.
