Microsoft CEO Steve “Sweat” Ballmer said that the financial crisis will “sap consumer and business spending,” leading to a downturn in Microsoft’s revenue. He explained that no company will be immune to the crisis although analysts predict an 8 percent rise in revenue this quarter.

He explained that none of the business units within MS will go to “0″ but that companies holding down spending while the crisis blows over will definitely not be buying Windows Vista Ultimate. This goes double, obviously, for consumers.

“On the other hand, when businesses have less money — they can borrow less money, they can spend less money — that can’t be good. When consumers feel the economic pinch, house prices come down. That can’t be good,” Ballmer said.
