What is a Windows Modern App?
Windows 8 and Windows 10 can be a bit confusing because they can run two completely different kinds of applications: Modern (also called metro, full screen, or even Windows Store apps) and Desktop (sometimes referred to as Classic) applications. On Windows 8 and 8.1, Modern and Desktop applications were pretty clearly separated but with Windows 10, there's much less of a separation between the two types of applications.
Modern Windows 8 / Windows RT / Windows 10 App
A Windows Modern app (aka metro, full screen, or Windows Store app) is a new type of application that runs on Windows 8, Windows RT, and Windows 10 PCs and tablets. Unlike traditional Desktop (or classic) apps, a Modern app has a single, chromeless (i.e., no outside frame) window that fills the entire screen by default, on Windows 8.1. See "Which Windows is right for you?" for more information on Windows 8 and Windows RT. On Windows 10, Modern apps can start in a Window, and if not full screen, tend to have a hamburger menu and a title in the upper left.
eWallet® for Windows 8/10 was designed specifically for these new devices so it won't run on Windows 7, Vista, or XP. eWallet for Windows 8/10 (and Windows RT) is available exclusively through the Microsoft Store.

What's a Desktop App (or Classic App) then? Desktop Apps are built for the Windows 7, 8 and 10 Desktop. eWallet for Windows PC will run just great as a Desktop App on Windows 10, Windows 8, and of course it will continue to run on Windows 7 as well. eWallet for Windows PC will continue to be available directly from Ilium Software.
