Windows 8 fails to spark Microsoft back into life.

Microsoft (MSFT) experienced a mixed FQ2 as it introduced its new Windows 8, which helped increase revenue at the company's OS unit by 24% to $5.88B. However, Microsoft's net profit slipped 3.7% to $6.38B, EPS of $0.76 just about topped expectations, and revenue edged up 3% to $21.46B but slightly missed consensus. "Business PCs are growing faster than consumer, emerging markets are growing faster than developed," said CFO Peter Klein. Shares were -1.6% premarket.
