Hi Brian,
In Windows 11, the Start menu has been redesigned. You need to click the all button, then the alphabetical list would appear.
Improvements to the start menu is on the way and rolling out.
Improvements and fixes
[Start menu] New! The redesigned Start menu, built to help you access your apps more quickly and smoothly. Its redesigned layout makes it easier than ever to find what you need.
Scrollable ‘All’ section: The main page now includes a scrollable “All” section, making it easier to find apps.
Category and grid views: Switch between two new views—category view, which groups apps by type and highlights frequently used ones, and grid view, which lists apps alphabetically with more horizontal space for easier scanning. The menu remembers your last selected view.
Responsive layout: The Start menu adapts to your screen size. Larger displays show more pinned apps, recommendations, and categories by default. Sections like Pinned and Recommended expand or collapse based on content. You can customize these views under Settings > Personalization > Start.
Phone Link integration: A new mobile device button next to Search lets you expand or collapse content from your connected phone. This feature supports Android and iOS devices in most markets and will roll out to the European Economic Area (EEA) in 2025.
