|---|---|---|
| Safety posture | Manual registry edits are error-prone and drift over time. | Governed policy application with reversible protection. |
| Persistence | Services can re-enable after updates or reboots. | Policy lock keeps services controlled. |
| Speed | Manual changes are slow and repeated per device. | Instant validation and consistent rollout. |
