I could write a really long post about the failings of the Chrome App API, but why bother; Google seems to have stopped listening to anyone.
Below is a guide to resources for doing Windows Web App Development.
General (BUILD 2015, why you might care about this platform):
I was present at the first Window NT developer conference, the Windows 95 launch, the (now infamous) "Cairo" conference and numerous other such events. The Build 2015 event was the most exciting (and I was attending this one remotely).

Getting started with Windows 10 Desktop Web Apps:
They provide a free book, geared at Windows 8.1, works well enough for Windows 10.
(Note to Google, this is called tutorial documentation... it is significantly more helpful than 3 minute fluffy videos.)
Windows API reference for Windows Runtime apps - Windows app development
(Note to Google, this is what a real API looks like.)
Pay particular attention to the alternate frameworks in this one. WinJS is rather fat, not really an issue on the desktop, but if you need to go lower-end, alternatives may be desirable. If you have existing code, the various projects can help, or at least give you CSS to help with styling.
"Project Spartan": Introducing the New Browser and Web App Platform for Windows 10 | Build 2015 | Channel 9
The Spartan browser will be the driver behind Windows 10 Desktop Web Apps... it is likely to be competitive with Chrome in standards implementation by the time it releases (it is getting close already, passing Chrome in ES6 features present, lags in HTML5 though).

So, from your server-based web app, did you ever want to let your users easily back up their data on a local disk? Access high-speed encryption? Real printing? The desktop notification system? This may blow your mind.
The Future of TypeScript: ECMAScript 6, Async/Await and Richer Libraries | Build 2015 | Channel 9
Tools to Help With Development (all are free):
Free Dev Tools - Visual Studio Community 2013
Visual Studio Code
- Visual Studio Code: A Deep Dive on the Redefined Code Editor for OS X, Linux and Windows | Build 2015 | Channel 9
- Works under Linux, Windows and MacOS.
- Developed using "Electron" (io.js and Chromium -- yes, that's right, Microsoft is shipping Chrome).
Whether or not you are developing for Windows, I recommend TypeScript for JS development.
- It also contains similar support for React, Knockout, AngularJS and Bootstrap.
- If you are not using one of these in your existing code, I suggest you take a look at the Bootstrap CSS there for hints on styling.
- I would only use WinJS full-blown for apps I was aiming at the Desktop/Laptops and high-end tablets and phones. It would take nearly two seconds just to parse the JS/CSS to DOM on a low-end phone.
- I haven't tried it yet, but consider using zepto instead of jQuery if you go the winjs-bootstrap route.
- Microsoft allows you to use any framework you like in you app, but strongly encourages you to blend in with the platform. (I'll have to agree that most customers would likely prefer that, so it is in your best interests.)
