Hi there,
You're right. That "Certificate Enrollment" message is a system-level pop-up from a Windows process (taskhostw.exe), not a regular app notification. It's designed to be a temporary dialog that just disappears, which is why it doesn't get saved in the Action Center.
Because of this, it’s expected that it won’t appear in the Notification Center history once it’s automatically dismissed. It’s designed this way since certificate renewal alerts are treated as one-time actionable system prompts, not user-level notifications meant for later review.
At present, there isn’t a configurable policy or registry key to change this behavior in Windows 11 even in build 26100.7019. However, for environments that rely heavily on certificate enrollment workflows, many administrators use custom scripts or endpoint management tools (like Intune or GPO) to deliver supplemental notifications or logs for tracking renewal prompts.
Thanks again for your great testing and attention to detail!
