After revealing a suite of ARM-powered laptops last year, we’ve been wondering how these Windows 10 machines would differ from their traditional brethren. Now we know: Microsoft accidentally published the “limitations” of Windows 10 on ARM last week before removing the documentation over the weekend.
Microsoft debuted the first batch of ARM-based Windows 10 devices in early December. Built by Asus, HP, and Lenovo, these laptops run off of a Qualcomm Snapdragon 835 processor. The main benefit of the switch from an x86-based processor is battery life: These laptops are intended to achieve upwards of 20 hours of battery life. Other differences the processor switch-up would introduce were less apparent.
- 64-bit apps won’t be supported, although support is anticipated at a later date.
- x86 drivers won’t be supported, even though Windows 10 on ARM can run x86 apps. (This should only be an issue if you’ve got older hardware accessories.)
- Some apps and games won’t work—specifically, those that run a version of OpenGL later than 1.1, require hardware-accelerated OpenGL, or games that use certain anti-cheating technologies, as The Verge notes.
- Apps coded for Windows Phone may also not work correctly.
- Hyper-V, Windows 10’s virtual machine platform, won’t be supported.
- And apps that customize the Windows 10 experience, for example, those designed to offer assistive technologies won’t work unless they are natively recompiled for ARM.
So for the most part, your favorite apps and games should run just fine—there are just a few fringe scenarios where some users may run into issues. In time, many of those problems will be moot as developers update their apps to support both x86 and ARM.
However, the true test will be once we get some hands-on time with these devices to see how their performance fares in the real world.
