Both Windows 8 and Windows 10 include apps ( e.g. calculator, camera, maps, mail).
Apps work differently to programs, so cannot be launched from Grid 3 using a Start program command on its own.
We have created an app launch grid set, which you can copy cells from to add into your own grid sets. You can find it here: Windows App Launcher grid set
You will see that these cells use the Start program command alongside Windows PowerShell and the relevant app code. We have collated a list of the app codes for the default Windows apps in the table below.
