Of course, the report's numbers also suggest Microsoft will strongly benefit from Vista sales in the E.U. market. The study says the upcoming operating system will be installed on 30 million PCs in the six countries within the first year of release, representing nearly a third of Microsoft's expected 100 million worldwide Vista sales for that time period. Those six countries only account for 65% of all technology spending in the E.U. economic zone, so if the adoption rate for Vista is the same in countries that make up the remaining 35%, the E.U. economic zone will account for over 46% of Microsoft's global Vista sales between January 2007 and January 2008.
