Hi,
Windows 11 does not include the “Show agenda” shortcut in the taskbar calendar flyout like Windows 10. The feature was removed as part of a design simplification and resource optimization. Instead,
you can view upcoming events through:
Widgets panel (add the Calendar widget for quick agenda access)
Calendar app (full-featured scheduling)
If you want the old experience, you’ll need to use Widgets or a third-party tool to replicate it.
I hope this helps!
