In the fiscal third quarter, Microsoft showed its reliance on cloud computing and other business services which now drive its earnings, in contrast to its earlier days when it focused on consumer PC software.

"Leading organizations of every size in every industry trust the Microsoft cloud," chief executive Satya Nadella said in a statement.

Commercial cloud revenue rose 41 percent from a year ago to $9.6 billion, which now makes up nearly a third of sales, Microsoft said.

Some $10.2 billion in revenue came from the "productivity and business services" unit which includes its Office software suite for both consumers and enterprises, and the LinkedIn professional social network.

The "more personal computing" unit which includes its Windows software, Surface devices and gaming operations generated $10.6 billion in the quarter.
