How to Tell if wmtray-ui is Legitimate or Malware

- Background Icon Updates: Apps provide icon state changes and tooltips which wmtray-ui renders in real time.
- Startup and Sign-in: wmtray-ui is loaded to display system icons as soon as you sign in.
- Notification Center Updates: New notifications or quick actions trigger tray refreshes to reflect state.
- Theme and Accessibility: Theme changes or accessibility adjustments may refresh tray visuals and contrast.
