STATUS_WOF_WIM_RESOURCE_TABLE_CORRUPT

The WIM resource index no longer describes usable data

A WIM image stores file content in resources and uses metadata to locate and interpret them. WOF-backed files depend on that mapping when a read is satisfied from the external image. This status indicates that the image-level resource table is malformed, inconsistent, or points outside valid data, even if the top-level WIM header can still be read.

Failures can affect many externally backed files that share the same WIM. Repeatedly replacing individual stub files is therefore unlikely to solve the underlying problem. The correct unit of diagnosis is the registered backing image and the storage path that contains it.

What to inspect

Determine whether failures cluster around one WIM GUID, data-source ID, or image index.
Validate file size and hashes against the known deployment or recovery image.
Check for media errors, incomplete servicing, interrupted image replacement, or unexpected cleanup software.
Use supported image verification or replacement rather than attempting to reconstruct resource offsets.
