Windows Very light on details, but this is interesting nonetheless - very interesting, and potentially one of the biggest things to have hit the operating systems business this decade. Bloomberg is reporting that Microsoft plans to announce Windows for ARM processors at CES in January 2011.

RE[3]: what's the point?

Of course not because *BSD/Linux already run on almost every CPU architecture out there. Desktop incarnations of Windows runs on exactly one. That is a desperation move and Microsoft has a lot of work cut out for them to be even remotely competitive. From a performance perspective they'll also face similar issues as they do with netbooks but even more so.

Windows NT kernel is built to be portable (there is a version of Windows XP for Itanium and Windows Server 2008 for Itanium also). The diagram below is the Windows 2000 architecture, I have seen similar diagrams for Windows VISTA & 7, but I couldn't find it with a 2 second google. However it illustrates the point.

Notice at the bottom there is a Hardware Abstraction Layer. This is where I would imagine (I am a web developer not systems developer so I can't say for certain) most of the main development will be in porting Windows to ARM (if it does indeed happen).

Secondly, Windows 7 & Windows 2008 R2 are highly modular e.g. We have Windows 2008 R2 servers which boot up without the windows shell, i.e. DOS prompt and not much else, you pretty much need to know powershell to interact with it. I don't doubt they will customise the build to include what is necessary.

Thirdly Windows 7 already support multitouch, and they already have a touch based UI with Windows Phone 7.

I agree with the other poster I doubt this is a desperate move, I think it is a pro-active one.
