ms-settings.exe is the host executable for the Windows Settings app. It starts when you open Settings from the Start menu, action center, or Run dialog, and it coordinates navigation to individual settings pages via ms-settings: URIs.
ms-settings.exe hosts the Settings UI and launches the appropriate Settings page when a user selects a category or uses a ms-settings: URI. It runs as a lightweight host and loads content from the Settings app package.

- Page Renderer: Renders and navigates individual Settings pages as you browse
- URI Handler: Interprets ms-settings: URIs and opens the requested page
- Background Tasks: Performs non-UI background operations related to Settings (e.g., policy checks)
- Notification/Telemetry Subsystem: Sends Windows notifications and telemetry signals related to Settings activity
