// App windows on Windows have an App User Model Id (AUMI) property. This is set

// opened. Windows desktop shortcuts have an app model property, and this should
// match the open window's AUMI. Windows groups open windows with the same AUMI
// to a taskbar icon. The two methods below are used  to create AUMI's for
// shortcuts and open windows. There are two kinds of windows, Chromium windows,
// i.e., browser windows, and app windows, which include web apps,
// extensions, i.e., windows opened via --app-id or --app.

// strings.

// app name and profile path. The returned app id format is
