Microsoft has slammed claims by Intel's Renée James that Microsoft will develop four different versions of Windows 8 for devices with ARM processors as "factually inaccurate and unfortunately misleading".

James, general manager of the software and services group at Intel, made the announcement at Intel's Investor Meeting 2011, which took place at the company's headquarters in California this week.
"There will be four Windows 8 SoCs for ARM. Each one will run for that specific ARM environment, and they will run new applications or cloud-based applications," she said.
"They are neither forward- nor backward-compatible between their own architecture - different generations of a single vendor - nor are they compatible across different vendors. Each one is a unique stack."
She also said ARM devices would not be able to run older Windows apps.
"Our competitors will not be running legacy applications. Not now. Not ever," she said.
However, Microsoft told Business Insider James' comments were inaccurate.
"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," Microsoft said.
"From the first demonstrations of Windows on SoC, we have been clear about our goals and have emphasised that we are at the technology demonstration stage. As such, we have no further details or information at this time."
