WaaSMedicSvc – Failed to Read Description – Error Code 2

In your Windows 11 computer, when you open the Services console, the Windows Update Medic Service may be missing from the list. When you scroll the services list, you may note that it is listed as WaaSMedicSvc instead of its actual display name — Windows Update Medic Service.

Also, the description column for WaasMedicSvc may show the following error:

<Failed to Read Description. Error Code: 2 >

waasmedicsvc error 2 description


<Failed to Read Description. Error Code: 15100 >

waasmedicsvc error 15100 description


Error 2 means ERROR_FILE_NOT_FOUND. Error 15100 means the DLL doesn’t have the specific string resource embedded into it.

The Windows Update Medic Service’s “DisplayName” and the “Description” registry values point to WaaSMedicSvcImpl.dll. In Windows 11 22H2, the module may not exist in most systems.


Even if you manually restore the missing WassMedicSvcImpl.dll module or by running SFC, you’ll see the error code 15100 for WaasMedicSvc. This is because the DLL doesn’t have the specific string resource (100 and 101) embedded into it.
