Tonight is the night. At least it is for Microsoft (Nasdaq: MSFT), which is on deck to report second-quarter earnings results tonight after the close.

Last quarter, the software giant reported record first-quarter sales of nearly $17.4 billion, which resulted in $0.68 in earnings per share. This bottom line was exactly what analysts were expecting, down to the penny. The Redmond giant had reported strong Windows 7 momentum, with over 450 million licenses sold since the operating system's launch. Microsoft had also given a sneak peek of Windows 8 at its BUILD developer conference late last year.

(Analyst) survey says...
On average, analysts are expecting earnings of $0.76 per share, with estimates ranging between $0.68 and $0.80. Of the 38 analysts covering Microsoft, 14 rate it a buy and another nine think it will outperform. One of them has slapped a sell rating on it, and another 14 consider it a hold. Although I'm far from a Wall Street analyst, I also recently gave it a hold rating.

Top-line revenue is expected to be about $20.9 billion, with high and low estimates of $21.4 billion and $20.2 billion.

Blame the floods
One of the headwinds that Microsoft likely faced during the quarter was the Thai floods, whose effects have rippled throughout the PC industry. The disaster left the hard drive industry in shambles, and it's awfully difficult to sell a PC running Windows without a hard drive. Chipmaker Intel (Nasdaq: INTC) also recently cut guidance due to the floods.

The who's-who in tech
Speaking of Intel, the chip king is also set to report earnings tonight. That's not all, though. To round out the list of major tech giants reporting tonight, also keep an eye on IBM (NYSE: IBM) and Google (Nasdaq: GOOG), since they'll also be putting up digits this evening.
