WU_E_NOT_APPLICABLE
WU_E_NOT_APPLICABLE means that the requested operation was not performed because there are no applicable updates. It does not state that a download failed or that the client could not contact the update service.
What to check
- Confirm the product, architecture, installed state, and update selection used by the request.
- Refresh the search result before deciding that the update should have applied.
- Use the update's applicability information rather than forcing installation of a non-applicable package.
Applicability is an evaluated device state
Windows Update uses metadata rules to decide whether an update is installed, superseded, or installable for the current system. MS-WUSP documents applicability rule elements for drivers, MSI applications, and patches, among other update types. A “not applicable” result therefore should be correlated with the current revision and device state rather than interpreted as a corrupt download.
When deployment software receives this code for a previously selected update, perform a new search and compare the update identity and revision with the earlier selection. A prerequisite may have completed, a superseding update may now match, or the device state used by detection may have changed. For private catalogs, inspect the applicability metadata when many expected devices reject the same revision.
