We’ve announced before in several venues that we’re all-in on PWAs. In fact, as hinted above, we want to take PWAs on Windows to the next level, by making them first-class app citizens in Windows. This follows from our general philosophy that the web platform, powered by EdgeHTML, is a core part of the Universal Windows Platform on Windows 10. Because of this any device running EdgeHTML 17 gets full access to the technologies and characteristics of Progressive Web Apps.
On other platforms, PWAs primarily originate from inside the browser, and can escape the browser in response to various prompts or menu options. We’re taking things one step further on Windows! Because a PWA can be a first-class citizen in the Windows Store, a user will be able to engage fully with an installed PWA—from discovery, to installation, to execution—without ever opening the browser.
On the other hand, in the browser context, all the benefits of being a PWA should still accrue to the web site, empowering the user to choose how and where they want to engage with the experience.
