Intel: Windows on ARM won't run 'legacy apps' • Channel Register

Microsoft may be porting Windows 8 to the ARM architecture,
but the general manager of Intel's software and services group insists
she's not losing any sleep over a bruising battle in a more-competitive
arena. At least when it comes to PCs.

Speaking on Tuesday at Intel's Investor Meeting 2011 in Santa Clara,
California, Renée James pointed out that the next version of Windows
– popularly known as Windows 8 – will be available in versions for both
x86 and ARM. There will be a "Windows 8 traditional", she said, that
will run on x86 chips and handle "legacy applications", meaning existing
x86-based Windows apps, and there will be a separate version of the OS
that runs on ARM. Windows 8 traditional, she explained, will include a
"Windows 7 mode".
