Microsoft has Windows running on Arm already

Written by Nick Farell

Wintel alliance sobs into its beer and remembers the good old days
Software giant and former president of the Intel fanclub Microsoft has said that it has run Windows OS on a 1GHz ARM chip. Earlier this year Redmond announced that they would be working hard to introduce support for the increasingly popular ARM architecture.

While departing from the x86 obessessed world, it would give Microsoft access to machines running Qualcomm Snapdragons, Apple A5s and Samsung Hummingbirds. The cosy relationship between Microsoft and x86 architecture, which lead to the successful Wintel alliance, is starting to cost Microsoft.

X86 does not work well on mobile gadgets because of its high power draws and inefficient cooling.  However the demonstration of Windows running on an Arm chip at the  MIX Developer Conference in sunny Las Vegas,  shows that Microsoft is serious about getting its software onto as many devices as possible and it does not care if it upsets Intel in the process.

Problem is with running on an ARM chip is that you'll need separate drivers and programs that are also capable of running on ARM chips, current programs for windows will not work as they're x86/x64, kinda like trying to run a mac program on windows, so the low down is if you get an ARM system running Windows then that's probably all you'll get unless developers are willing to write programs solely for Windows on ARM chip

What no Tegra mentioning? Oh ah I c because it is not Fuad writing this article. Well Atom actually is doing a hell of a lot better in the power/performance departmnet since version 1 so your statement above are a bit misleading.

I think .NET will be Microsoft's answer for ARM/x86 incompatibiliti es... I also think it is possible to run x86 code on ARM in a virtual environment.

Morgan Stanley upgraded the rating on this stock this morning based on the Vegas demo so investors seem happy with this.

For those interested :)

Quoting yourma2000:

Applications written using the .NET Framework won't have these issues, unless of course the developers used a architecture specific P/Invoke.

Well we all knew this was coming. Microsoft has been saying that Windows 8 will be ARM compatible for some time.
Like people have been saying. The biggest problem will getting X86 emulation to run well. So that games and applications that don't use .NET frame work run smooth.

If MS is jumping into arm products it won't do it half assed. Odds are MS has developed software that compiles for android devices and powerVR.

The only way windows will be competitive with other mobile OSes is if it keeps Windows on arm "close to metal" Speed wise it's the only choice.
