You don't. It seems others do: http://redmondmag.com/articles/2009/10/08/rumor-windows-8-will-be-128-bit.aspx

The PR departments has strange hardware requirements.


128-bits may apply to something besides memory addresses. Although, it is hard to conceive of a need for 128-bit precision in arithmetic ops.

Some CPUs are internally actually VLIW[0] machines, even if they present a standard architecture to the outside world.

Microsoft may be doing infrastructure work that will not see the light for 20 years or more, if ever. But, better to do it now than later. The Y2K thing comes to mind here. Also, they may want to see Windows running on serious supercomputing iron. (For PR reasons, of course.)
