OK, time to cool your jets: Yes, Windows 10 can run natively on ARM platforms... with some limitations. Microsoft has released documentation outlining exactly what those restrictions are and well, there's a lot.
Probably the biggest limitation is support for x64 applications. While x86 emulation is available, Windows 10 on ARM won't have a bar of its bit brother (terrible pun intended).
Understandably, drivers must be complied for ARM to work and any program that assumes you're running Windows on a desktop platform will likely explode:
As with all architectures, kernel-mode drivers, User-Mode Driver Framework (UMDF) drivers, and print drivers must be compiled to match the architecture of the OS. ... Native OS components cannot load non-native components. Examples of apps that commonly do this include some input method editors (IMEs), assistive technologies, and cloud storage apps. IMEs and assistive technologies often to hook into the input stack for much of their app functionality.
Some 3D games may also run into trouble, as only OpenGL 1.1 is supported... and that's not even hardware-accelerated apparently. Good news on the DirectX front however: APIs from 9 to 12 (so all the relevant ones) will work fine for x86 applications.
Finally, forget about virtual machines using Hyper-V. Not that surprising, considering there's enough emulation going on as it is.
Microsoft has a small troubleshooting section available, which you'll find on the same page.
