Hello,
If the new Start Menu does not open automatically in Windows 11, 25H2, and 24H2, please force enable the new Start Menu.
ViVeTool is an open-source tool that can manually enable hidden features (including the new Start menu). It works by calling Windows’ official Feature Management API to toggle feature flags, rather than modifying system files, so it is relatively safe — but you must use the correct feature ID.
For details, you can refer to:
