To enable the Windows 11 new Start menu, start by checking if it's available for you. Navigate to Settings > Windows Update > Advanced options > Optional updates, and install KB5067036 (it requires Build 26100.7019 or higher). Restart your PC, and it should appear.
If it doesn't appear, you may manually download the KB5067036 to install through Microsoft Update Catalog. Just enter the KB5067036 to Search form then choose the package right for your system.
Then download the latest ViVeTool package from its GitHub page and extract it. Open Command Prompt as an administrator and navigate to extracted location then run this command:
vivetool /enable /id:47205210
Restart your computer, and you should see the redesigned Start menu.
