A day after an Intel executive talked extensively about Windows 8 at its investor meeting, Microsoft went on the record to say Intel was off base with its remarks.

Intel's senior vice president, Renee James, told investors and analysts this week that the upcoming version of Windows 8 running with ARM based chips will not be able to carry legacy apps. The company's chief executive, James then said a real PC is one that can run legacy apps, thus suggesting any ARM based operating system on a PC isn't legitimate.

Turns out, Intel's ARM bashing didn't sit well with Microsoft. The Redmond, Wash. based company has come out with a stern response against the famous chip-maker.

Intel's statements during yesterday's Intel Investor Meeting about Microsoft's plans for the next version of Windows were factually inaccurate and unfortunately misleading. From the first demonstrations of Windows on SoC, we have been clear about our goals and have emphasized that we are at the technology demonstration stage. As such, we have no further details or information at this time, a Microsoft spokesperson said to Business Insider.

Microsoft made the point that Windows 8 is merely at the demo stage with nothing set in stone. Thus while Intel's assertion about legacy apps could be true, right now it is not. James during the meeting also said there would be four different versions of Windows 8, each running on a different brand of chip. Another fact that was disputed by Microsoft.

At the Consumer Electronics Show, Microsoft introduced a demonstration of what Windows on an ARM-based chip would look like. Beyond that, the company has not detailed the difference between the ARM based OS and the Intel x86 OS.

Intel also took at AIM in the area of smartphones and tablets as well. The company made it a point to tell analysts and investors that is has no plans to go down the same path as some of its rivals, notably Nvidia, Qualcomm and Texas Intstruments, and use ARM processors to build a more mobile friendly chip.
