Confusion Surrounds Windows 8 ARM Support for Desktop Apps
Company mum on rumors on Windows 8 plans.
Microsoft's may be reconsidering its plans to support both "Metro-style" and legacy "Desktop" applications on ARM-based Windows 8 tablets
Long-time Microsoft observer Mary Jo Foley wrote that Microsoft is leaning toward "cutting the Desktop [app support] from Windows 8 ARM tablets." The information originated with Foley's Windows Weekly podcast partner Paul Thurrott but has not been confirmed by Microsoft.
The concept doesn't come as a surprise; most users expected that legacy applications designed to run on x86 hardware would have to be recompiled to run on Windows 8 and ARM hardware, but such a requirement could strain many independent software vendors. Although most people may not have believed that ARM would be supported for legacy desktop apps on Windows 8, Foley got the message that Windows 8 would nonetheless support it.
Microsoft has stayed mum about its Windows 8 plans since September except for releasing feature descriptions on its building Windows 8 blog. The communications to Foley have contradicted what Steven Sinofsky, president of the Windows and Windows Live Division, has said.
"We've been very clear since the very first CES demos and forward that the ARM product won't run any X86 applications," Sinofsky told financial analysts at the September Build Conference for developers. However, what Microsoft had shown at CES in January was Microsoft Office running on an ARM-based notebook running the "Windows Next" operating system and printing a Word file, so the issue of support remains muddy.
In essence, if Microsoft's ISV partners don't plan to recompile their x86 applications for Windows 8 ARM machines, then there would be no reason for Microsoft to build such a Desktop UI for that OS. And Microsoft appears to have decided not to support legacy apps on Windows 8 ARM anyway.
A spokesperson for Microsoft explained via e-mail that "Microsoft is not commenting publicly on this topic."
