Microsoft is testing a redesigned Start menu for Windows 11 that includes new layouts for the app list, such as a grid and category view. Users will not be able to create personalized category types, as Windows 11 will determine app categorization, potentially leading to an 'Other' section for apps that do not fit defined categories. Users cannot move apps between categories, which limits customization. The Start menu is still in testing, and there is hope for future enhancements, including drag-and-drop functionality, in the upcoming Windows 11 25H2 update.
