Nearly all tutorials on the Adafruit Learning System are written such that the user can use the web version of MakeCode. The web version runs on multiple computer types providing broad compatibility.
There is another version of MakeCode available from Microsoft in the form of an app that runs on Windows 10 and Windows 11 machines.
The Microsoft MakeCode App is located in the Microsoft App Store.
In the Windows Search bar (usually next to your Start Button), type "Microsoft Store". In the search bar for the store app, type MakeCode. Select MakeCode for Adafruit.
Click the Install button for MakeCode for Adafruit. The app will install and you can then press the Launch button.
