Notification store failure: Action Center toast persistence in Windows 8.1

Windows 8.1 utilizes the Action Center to aggregate toast notifications from Modern UI applications. While per-app toggles in PC Settings allow for basic noise reduction, the system lacks native support for priority levels or time-based suppression (quiet hours).

A documented limitation exists regarding the notification store's reliability. When toasts are dismissed or when the history buffer reaches its limit, critical alerts may not be reliably re-surfaced, leading to a potential loss of important system or app events.

Constraints

• Modern UI app notifications are routed through the Action Center.
• Win32 desktop applications continue to use legacy balloon tips, bypassing the Action Center.

Given these architectural differences, how can a user ensure critical Modern UI alerts are preserved without allowing non-essential toasts to flood the bounded history? Is there a documented method to prevent the notification store from purging high-priority alerts during high-volume noise events?
