Here's what you can and can't do with Windows 10 on ARM

Here's what you can and can't do with Windows 10 on ARM

Additionally, only ARM64 drivers are supported, which will limit hardware compatibility.

If you follow this link you won't find the limitations listed anymore though the link ( still mentions limitations in the URL.

Back in December, the first Windows 10 on ARM laptops from Asus and HP were revealed during Qualcomm's Snapdragon Technology summit, and both machines are expected to be released later this year. This exposure came via Microsoft's official documentation and mow, Microsoft has tried to do damage-control by editing the documents and removing any references to Windows 10 on ARM limitations. Well there are several big ones, one of them being the lack of support for x64 apps, and the lack of x86 driver support.

Apps that "customise the Windows experience may not work properly" on this flavour of Windows 10 either, Microsoft cautions.

The document still warns that x64 apps won't work on Windows-on-ARM, that x86 drivers will need to be re-written for ARM and that apps reliant on either OpenGL version later than 1.1 or hardware-accelerated OpenGL will struggle. "For more info about compiling your driver for Arm64, see Building ARM64 Drivers with the WDK". They all need recompilation specifically for Windows 10 on ARM, which is likely to happen for anything popular or paid-for.

Seifsa anxious about potential impact of proposed USA steel import tariff increases
This provision imposes a high rate tariff due to national security reasons and will inevitably hamstring Korean steel exporters. The issue is getting increasingly serious as the US considers tariffs and quotas for steel and aluminum imports.

Certain types of apps that customise Windows may not work correctly because native OS components can not load non-native components, it said. Microsoft notes that "certain games don't work", as well.

In what will surely be a disappointment to folks who want to virtualize everything, Hyper-V is not supported on Windows 10 on ARM.

If there was something I've been excited over more than most things in the technology industry, but the thought of Windows 10 on ARM was doing amusing things to my body. Native OS components can not load non-native components. Games that use anticheat technologies also won't run on Windows 10 on ARM.

The document, "Limitations of apps and experiences on Arm" appeared on Friday on Microsoft's Windows Dev Center, quickly gaining coverage because Microsoft hadn't yet explained how Windows 10 on Arm would be different to Windows 10 on x86, and what type of performance impact emulation would have on apps. Cloud storage apps may not work because they often use shell extensions, such as icons in Explorer, which may fail. Hyper-V, formerly known as Windows Server Virtualization, is used to create virtual machines on x86-64 systems running Windows.
