how to change windows to 64 bit windows 10

UWP applications from the Store have been compiled into native ARM code, but x86 code runs in emulation, on top of the WOW ( Windows on Windows) abstraction layer. So do the NTDLL system services that let apps talk to the kernel, and system DLLs for storage, graphics, networking, and other device drivers that talk to the kernel, which means they get native hardware speed. Windows itself - both the Windows kernel and the features inside Windows like the shell and File Explorer - runs as native ARM 64 code. So how does that work, and how well will it work? Windows on Windows on ARM Install Windows 10 Pro and you can install standard Windows applications, with only one real limitation: even though it's a 64-bit version of Windows and the Snapdragon 835 is a 64-bit Kryo CPU, only 32-bit x86 applications are supported - not 64-bit 圆4 code. There's also a free upgrade to Windows 10 Pro - not a special or limited version of Windows, but the full Windows 10 Pro that Microsoft has compiled for ARM. Although the first systems to go on sale will all come with Windows 10 S, which only runs apps that come from the Store, those Store apps can include standard desktop x86 apps that have been packaged up for distribution through the Store. They use 64-bit Snapdragon 835 SOCs (which Qualcomm calls a 'Mobile PC Platform') and they can run many more applications. The new Windows on ARM devices that are about to go on sale aren't taking the same approach. But not running standard Windows programs - either recompiled or in emulation - was an artificial limitation (although designing Windows RT devices just for Store apps meant they used rather underpowered Tegra SOCs that couldn't have delivered good emulation performance anyway). The idea was to turn Windows in a OS that was designed for mobile - like iOS - to get better security and battery life. Development continued for ARMv7 32-bit processors with VFP floating point, NEON (ARM's version of Intel's SSE instructions for processing data in parallel) and the Thumb-2 instruction set.īut when that shipped as Windows RT, it only ran apps that had been specifically written and compiled for ARM using only the WinRT APIs. Older versions of Windows ran on PowerPC, Alpha, Itanium, and MIPS, after all, and in 2009 an unofficial internal project had Windows 7 running on ARM. Windows on ARM isn't new: from Windows Phone to Windows RT to Windows IoT, Microsoft has had multiple systems that take Windows beyond the familiar Intel and AMD processors.
