Thank you very much for your information and insight. If you are speaking specifically in developer nomenclature, I can understand how this may be confusing, but remember this article is intended for an IT Pro audience which usually differentiates application types more broadly. When we speak of apps in the IT Pro context, we avoid the semantic jungle and focus on applications from a management perspective and not a developer one.
Referencing this documentation, we generally classify from an app management perspective the app types on Windows 10:
- Windows apps - introduced in Windows 8, primarily installed from the Store app.
- Universal Windows Platform (UWP) apps - designed to work across platforms, can be installed on multiple platforms including Windows client, Windows Phone, and Xbox. All UWP apps are also Windows apps, but not all Windows apps are UWP apps.
- "Win32" apps - traditional Windows applications.
With regards to your confusion re: "inbox apps." I will clarify and use the more appropriate terms "system and provisioned apps." 🙂
