WU_E_DM_SANDBOX_HASH_MISMATCH

WU_E_DM_SANDBOX_HASH_MISMATCH indicates an integrity mismatch in the staged download environment. The safe outcome is to reject the current state and obtain verified content again after identifying the source of inconsistency.

How to investigate

  • Check preceding disk, antivirus, cache, BITS, and content-delivery errors for the same update attempt.
  • For WSUS or intermediary caching, verify that clients receive the current, unmodified payload and metadata.
  • Do not suppress validation or reuse the suspect staged content.
