STATUS_ILL_FORMED_SERVICE_ENTRY
The Service Control Manager data does not describe a valid driver service
Kernel drivers are described under the Services registry tree. Values such as service type, start mode, error control, image path, dependencies, and group membership must form a coherent entry for the driver package and boot phase.
This status usually points to an incomplete INF installation, manual registry editing, failed rollback, or mismatched package version. Copying values from another driver is unsafe because load order, binary path, and service type are component-specific.
What to inspect
- Compare the Services entry with the installed INF and cataloged driver package.
- Verify ImagePath resolves to the intended signed binary.
- Check Type, Start, ErrorControl, dependencies, and load-order group together.
- Reinstall or service the owning driver package instead of inventing missing values.
