To get this new Start menu, you must be running build 26100.7019 or 26200.7019 or newer versions of Windows 11. Make sure you have all the latest updates installed by going to Settings->Windows Update and clicking the Check for updates button. You can check your Windows build number by hitting Windows+R to open the run prompt and running winver. //

If you have the right build number, it’s possible that the new Start menu will appear on its own. But, if not, you can use the ViveTool, a utility that enables hidden Windows features, to turn it on.

First, download the ViveTool and unzip it to C:\vive. Then open a command prompt as an administrator and change into that directory.

cd c:\vive

Finally, issue the following command:

 vivetool /enable /id:57048231,47205210,56328729,48433719
