Microsoft has revealed its financial results for the first quarter of 2009, up to September 30.

The company has announced a revenue of $15.06 billion, operating income of $6 billion, and net income of $4.37 billion.

The results show a revenue on increase of 9% from the same quarter last year, but when increased expenses are considered, the net income comes out at a 2% rise.

"In a challenging economic environment, the first-quarter results exhibit the strength and diversity of our business model," said Chris Liddell, chief financial officer of Microsoft.

Looking forward, Microsoft says in the current economic climate, they will focus on low cost of ownership, n expense management and "targeting investment into the highest priority strategic opportunities."
