Windows 10 on ARM promises to make laptop computers cheaper and longer-lasting than ever before. Running Windows 10 on ARM chips, the exact same silicon found inside smartphones, should make all-day battery life in a tiny form factor possible.
The million-dollar question has been exactly what those limitations are, and Microsoft just accidentally gave us the answers. Over the weekend, it appears that Microsoft accidentally published a support document outlining all the limitations of Windows 10 on ARM vs x The document was quickly pulled, but not before being scraped by web caches.
Here are all the limitations Microsoft outlined:.

First announced in Decemberthe company surprised everyone by partnering with Qualcomm in an effort to get Win32 apps running on ARM chips. A year later, the first devices to use the Snapdragon chipset were announcedbut those won't come to market until this spring. In other words, very few people have actually used one of these devices, so we're still relying on Microsoft and OEMs to tell us what to expect. This week though, Microsoft published some documentation regarding Windows 10 on ARM, and it described the limitations of the new platform.
Based on Windows 8, users could only use apps built for the Store. Windows 10 on ARM is quite different. These devices ship with Windows 10 S, so they still run apps from the Store, although the Windows 10 Store now takes Win32 apps that are packaged for it, and there's also a free upgrade path to Windows 10 Pro. But with Windows RT still fresh on many people's mind, we're still all curious about what the limitations of Windows 10 on ARM will be. The lack of support for bit Win32 apps has been known for some time.
The reason for this is because the emulation that Windows on ARM uses to get Win32 apps working on ARM processors is actually the same emulation layer Windows on Windows, or WoW that Microsoft uses to get x86 apps running on x64 machines. Developers may also want to call IsWow64Process2 from their apps.
The original IsWow64Process was used to tell if a bit app was running on a bit machine. Obviously, these were meant for PCs with Intel chips, so apps might be made to direct the user to download and install the bit version if the app detects that the PC supports it.
This allows users to create virtual machines, similar to a number of third-party options. Hyper-V on ARM isn't supported, and according to the documentation, you won't be able to create VMs at all, even with a third-party solution. Microsoft's Universal Windows Platform was built in an interesting way.
Developers are able to create one app with responsive design similar to a webpage. The app is then compiled for x86, x64, and ARM platforms, and distributed accordingly. In other words, if the app is built properly, Microsoft could expand Windows 10 Mobile to include x86 support, or expand Windows 10 PCs to include ARM support, and developers wouldn't have to rebuild their apps.
Obviously, not all developers follow best practices, and some may have written their code assuming that all ARM devices are phones. These apps might show in the wrong orientation, present other UI issues, or just crash altogether. One reason that this will happen is if the app tries to call mobile-only APIs.
For example, calling HardwareButtons could cause an issue. I don't know what games you were planning to play on your new Lenovo Miix with its Snapdragon SoC, but it turns out that some of them won't work.
Any game that requires a version of OpenGL later than 1.
Microsoft’s Windows on ARM Effort is Seriously Limited
Microsoft also says that games that rely on anti-cheat drivers won't work either. While apps can be emulated on ARM, drivers cannot. All "kernel-mode drivers, User-Mode Driver Framework UMDF drivers, and print drivers" must be compiled for the native architecture for the operating system.Originally Windows 10 as distinguished from Windows 10 Mobile could run only on PCs that were powered by x86 and x64 processors.
These PCs will provide great application compatibility and allow you to run your existing x86 win32 applications unmodified. This also includes all the device drivers such as graphics, networking, or the hard disk. This ensures that you get the best user experience and battery life out of your device running at the full native speed of the Qualcomm Snapdragon processor.
If you are a UWP developer, please ensure that you submit an ARM package for your app as this will provide the best user experience for the device. For more information see App package architectures. For more information, see this blog post. If you only submit the x86 version of your app, the OS will install that version and run it under emulation. For more information about architectures, see App package architectures.
Note that bit x64 Win32 apps are not supported, but the vast majority of apps have x86 versions available. When given the choice of app architecture, just choose the bit x86 version to run the app on a Windows 10 on ARM PC. You may also leave feedback directly on GitHub. Skip to main content.

Debugging x86 apps on ARM.When Microsoft announced it was working on a new version of Windows on ARM, the news generated a fair amount of skepticism. Windows RT looked just like Windows, but had few of the features or capabilities users expected and the backlash was fierce.
This time around, Microsoft declared it had learned from its own mistakes and written an emulation layer that would allow chips like the Qualcomm Snapdragon to run software written for x86 processors.
At first, this seemed like a win-win. Customers could tap new devices and compare ARM with x86 directly, while still being able to run x86 software on an ARM laptop. I applaud Microsoft for taking the time to bake an x86 emulator into code, but the company needs a better plan for disseminating this information. Windows RT bombed, in large part, because people bought it expecting one kind of device and got something vastly inferior. Windows 10 on ARM is trying to dodge that bullet, but there are major questions to be answered.
How well does the emulation practically work? Will emulation ever be expanded to handle bit applications? One of the best uses of technology is extending capabilities that help people with various disabilities engage with the world around them. Assistive technologies are a fundamental component of that process.

Windows 10 on ARM
Windows 10 ARM project for phones is getting even better January 5, WhatsApp will soon stop working on all Windows Phones December 31, We've reviewed a handful of laptops and tablets running on ARM chips, each of which offered long battery life and LTE connectivity but at the expense of performance. That was an unfortunate restriction put on users by Windows RT, Microsoft's watered-down operating system for 2-in-1 devices.
Microsoft shut the RT window years ago, now tablets simply run on Windows At this time, Surface Pro X will not install bit applications that have not been ported to ARM64, some games and CAD software, and some third-party drivers or anti-virus software. New bit apps are coming to ARM 64 all the time.
What does this mean for you? It will have all the same tools and interfaces when you first boot it up and even run most, if not all, of your apps. That's because most developers offer bit versions of apps along with their full bit versions. In our own experience, we found that 1Password wouldn't work correctly on the ARM-based HP Envy x2 and that the bit version of Chrome ran rather slowly.
We've also had all sorts of trouble running benchmarks on these devices. Generally, the apps only offered in bit are demanding legacy programs. Also, some third-party antivirus software can't be installed. The majority of people will come across a few roadblocks when using the Surface Pro X but will generally have the same experience as they would using a Surface Pro 7 or another Windows 10 device powered by a bit processor.
If the apps you use aren't bit only, then you shouldn't rule out the Surface Pro X. We'll have to wait for a review unit to see how Microsoft's performance claims hold up. If it can't, then it doesn't really matter which apps the Surface Pro X can run if it doesn't have the performance to do so in the first place.

Drivers are software programs that communicate with hardware devices—they're commonly used for antivirus and antimalware software, printing or PDF software, assistive technologies, CD and DVD utilities, and virtualization software. Peripherals and devices only work if the drivers they depend on are built into Windows 10, or if the hardware developer has released ARM64 drivers for the device.
Apps that customize the Windows experience might have problems. This includes some input method editors IMEsassistive technologies, and cloud storage apps.
Outlook The majority of people will come across a few roadblocks when using the Surface Pro X but will generally have the same experience as they would using a Surface Pro 7 or another Windows 10 device powered by a bit processor.
Microsoft Surface Pro X vs.Microsoft is collaborating with Qualcomm to get x86 Windows programs up and running on ARM chips, and it was during the summit we heard more about the project. Initially, it seemed as though Windows apps would run the same on ARM chips as on x86 chips. While Qualcomm was showing off the Snapdragon for upcoming smartphones, the Snapdragon received some love, too.
