Microsoft executives said this week that Windows 8 tablets using an ARM chip will not be able to run legacy Windows 7 applications, with the possible exception of Office.

This week, Microsoft held an analyst meeting in conjunction with BUILD, its developer conference in Anaheim, where the company talked more about Windows 8 and provided the first code to developers. (For more, see's hands-on of the Windows 8 preview.)

At that conference, however, Microsoft executives said they had made it "very clear" that Windows 7 legacy applications would not run on Windows 8-based ARM tablets - a fact that arguably hasn't been made clear at all.
