Sinofsky also said that the Windows-on-ARM machines will come with several Office apps — Word, PowerPoint, Excel and OneNote ...But Sinofsky said that, although those applications will run in the traditional Windows desktop, they will be the only programs
allowed to do so, other than components of Windows itself.
“There are no other compiled dekstop apps that are available,” Sinofsky told AllThingsD. All of the other apps for Windows on ARM will be the new-style “Metro” apps.
