Windows 8 and ARM is a marriage made in heaven. Microsoft has just released a press release about the ARM support of their upcoming operating system Windows 8 . The press release basically states that Windows 8 will indeed support System on a Chip (SoC) architectures on x86 and ARM architecture. Why Microsoft use ARM to Windows 8?
There are many reason from Microsoft why use ARM. But, Microsoft has been working to port Windows to ARM for several years. We had heard about LongARM, a project to port Vista (codenamed Longhorn) to ARM a while back. Microsoft last year signed an architecture licensing agreement with ARM, but wouldnt say anything about its plans at that time.
Microsoft is believed to be finally backing ARM as that low-power processor is especially well suited to tablets and slates, which are one of the primary form factors Microsoft plans to target with Windows 8. Windows 8 ARM can not run legacy applications, will give a fresh breeze to Intel after their market share in PCs, laptops continue to be undermined by the presence of Tablet Computers (Notebook) and Smartphones (Android and iPhone) that uses an ARM processor.
Since at least the corporate enterprise in the near future will not be moved using a computer were caused by the ARM processor is still using legacy applications tailored to their needs; although the possibility of Microsoft or third-party developers will create a legacy application emulator is still there.
