Universal Apps and the Windows Store

We just got done discussing why a single user interface for the OS across multiple devices is not always the ideal solution, so of course the obvious question with Universal Apps is why would you want it with the app model instead? Thankfully this is not the case although the term Universal App might lead people to believe they are attempting to have a single app target all of their platforms. The truth of the matter is that Universal Apps are Universal in the sense that they share a common app store.

If Microsoft is going to have Windows 10 succeed on desktops, laptops, tablets, phones, and even Xbox One, they need developer buy-in. A platform without apps is not much use to anyone. With the Universal App, they can bridge all of their platforms with a single App in the store. Under the hood, each app is created with a common framework of code, as well as multiple user interfaces in order to tailor the experience to the correct device type. Below is a screenshot of Visual Studio – Microsoft’s developer tools – with a new Universal App about to be created.

As you can see, there is a shared portion of code, and then a project for the UI for Windows 8.1, and Windows Phone 8.1. Xbox One is not available yet, but should be added in a future release of Visual Studio.

But you may be wondering why any of this is necessary. Windows has the largest selection of applications of any system ever. That is of course true, and the Win32 framework has served both Windows and its users well over the years. But with the new WinRT framework there are some big advantages. First, it can be written to in multiple languages including HTML. WinRT supports C++/CX, C#, VB.NET, and HTML scripting with JavaScript and TypeScript. The security model for WinRT apps is a lot different than Win32, with all WinRT apps running in a sandbox mode for higher security. Unlike apps written in .NET, WinRT is native code, which should result in better performance. Contracts and Extensions are also new to WinRT, and allow apps to share data while still being in a sandbox. One of the biggest advantages of WinRT is that it is DPI aware, and can automatically scale apps appropriately based on screen size and screen resolution. Here, as we know, Win32 apps can struggle even though there are solutions in place.

One of the biggest disadvantages of WinRT is that it is only available on Windows 8 and newer devices. With Windows 8 struggling in the market as compared to Windows 7, the user reach of a developer targeting WinRT apps in the Windows Store would be for a subset of the total user base. With Windows 7 having over 50% of the desktop OS market share to itself, this is going to be an issue.

With Windows 10, Microsoft is certainly targeting Windows 7 users. If they can convince them to upgrade to the latest version of the operating system, then the new environment will have a much larger target base and will hopefully encourage developers to target the Windows Store. We have not heard of any upgrade promotions or pricing yet, but this is one of the biggest advantages Apple has had over the years. Their user base generally upgrades the OS at a much faster uptake than Windows. This allows developers to utilize newer APIs in the latest versions of their operating systems and keep the platform progressing. Microsoft has already had to deal with people being stuck on Windows XP, and they must be wanting to avoid that with Windows 7.

Since we are discussing Universal Apps and their advantages, one of the biggest advantages is the Windows Store. With Microsoft hosting the entire download and purchase of all WinRT apps, having user settings and apps sync from one device to another is much easier. One of the greatest experiences with Windows 8.1 is signing into a new PC for the first time. When you log in with your Microsoft Account, the system asks you if you would like to copy the devices and apps from one of your other devices, or if you want to start with a clean machine. If you choose a previous machine, all of the settings, wallpaper, Start Screen layout, and Windows Store apps are synced to the new device. In the case of Windows Store apps, the app itself is listed on your Start Screen, but it is not downloaded until the first time you select it. This avoids a situation where you will significantly delay the initial login time with a massive download, as well as avoid filling the available storage with apps you may not need on that particular device.

Windows Store on Windows 8.1

Also, like modern tablet and smartphone OSes, WinRT apps from the store are automatically kept up to date by the store. This avoids a lot of the issues with viruses and malware attacking an older version of a product since in theory it will not be around any longer.

The one thing missing from this are the older Win32 apps on the desktop, because they are not available in the Windows Store. Prior to Windows 10, desktop apps could be listed in the store, but the store would then link to the developer’s website to allow you to purchase and install the app. With Windows 10, rumors are that desktop apps will also be available and managed through the Windows Store. Assuming this does happen, then this will be a major boon to users. Desktop apps should in theory also be able to be kept up to date using the Windows Store which should cut back on the number of outdated pieces of software targeted by malware.

The Windows Store is a key piece of Windows 10. Universal Apps can be made available for multiple platforms through the store, and, if the rumors are true, even desktop apps will be available through the store. This should make the Out Of Box Experience (OOBE) very good for users with a Microsoft Account. The WinRT framework has not yet had the killer app written for it, so hopefully with Windows 10 the framework will be expanded to allow for more powerful apps to be created.

    really it looks like a descent thing, microsoft has tried to solve the interface issue quite well by combining the features of Win 7 and Win 8 to make it more user friendly for the desktop users,, it looks a new avatar of Win 8 which is much more sustainable for the Win 7 users to switch to a new Win OS. Thats what Windows is all about. hope it bangs in the market as the Win 7. looking forward to this thing. Reply

    I am using this now on my laptop and I must say I am pleasantly surprised ! I did like the Windows 8.1 a little bit (I am a Linux user on my PC for over 6 years now) and desired to rest the version. Although the website says its a developer preview and should not be used on your main PC, it is very stable. Considering this is not even Beta( Build 9841).

    The updates are relatively less (for my 8.1 PC i get close to 500Mb updates a week), just about 12 Mb so far in a week. No crashes.

    Only issues observed - Very Old games (circa Unreal Tournament 1999) do not run even in backward compatibility mode with hardware rendering. And Google Dive sync does not work

    I am using the technical preview since two weeks or so. Love it to the core. Using it with ATI R7 240 gpu, 4GB corsair DDR3 ram. No issues whatsoever. Butter smooth. No major issues with drivers either. XBMC Gotham and other players run just fine. Dual display set-up also running great! MS has a winner. Reply

    And people like myself will reiterate: Windows 8 is viewed in a positive light by the majority of non-techies who have tried it. I have installed it on all but ONE of my machines and if Microsoft included Windows Media Center in Windows 8 without having to get the Professional version, I would have switched that one over as well.

    Now if MS could only program all the stuff back into their servers that they expect you to type with powershell I'll be thrilled. When is the last time someone here went to a command prompt and typed dir or del or ren? GUI is what made computers popular with normal people you f'n suspender wearing, Linux wannabes! Reply

    Most of the slated changes for Windows 10 seem like significant improvements tome and I'm relatively optimistic about the possibilities of moving the 200+ PC users to it (after the initial bugs, etc. have been shaken out). My biggest reservation is forcing access to WinRT apps through the Windows Store. I realize there are options for side loading but in my shop ( development house) eliminating the ability for a user to freely install an app when they choose could be a deal breaker.

    Beyond my company specific needs, for the home users, I can also the Windows Store only availability of WinRT apps being a major turn off and something that could significantly reduce the interest in WinRT apps for the general public.

    Windows 8 apologists usually end up talking about how it's "not that bad", and that it's ultimately functional after a long learning curve.

    Frankly, if Windows 7 didn't exist, most of us probably would be using Windows 8. However, Windows 7 does exist, and it's just as functional as Windows 8, but with a more desktop-user-friendly UI.

    So why would a Windows 7 user want to switch to Windows 8? If what it boils down is that 8 is a bigger number than 7, that's not a compelling argument. If I'm "upgrading" it should be to a better product, not one that is "only a little bit worse after you get used to it."

    "As an attempt to keep malware at bay, Windows 10 can only allow trusted applications to be run on it. That trust can come from Microsoft, or from OEMs and organizations. A company can sign apps themselves if they wish, choose apps signed by particular software vendors, apps from the Windows Store, or all of the above."

    Best feature by far. This could be a major kick in the pants for malware.

    i tried beta and don like the Windows 10 Edge browser... it is is broken

    this was previously known by the codename Project Spartan.

    With Edge you can’t save a web page as a web archive (which combines all the text, graphics and layout into a single MSHTML file). And you can’t pin sites to the Windows 10 taskbar, as you could with IE.

    it dosnt even do justice to some html 5 coded sites

    Thats my 2cents anyway
