Microsoft (MSFT) recently announced its fiscal Q2 2011 earnings, in which the company commented that its Windows 7 operating system continues to gain adoption amongst businesses. Roughly 90% of enterprise companies worldwide have begun their OS migration to Windows 7. Microsoft is the dominant player in the PC operating system market, competing primarily with Apple's (AAPL) Mac OS as well as open source software companies like Red Hat (RHT) and Novell (NOVL).

Following Thursday's market close, Microsoft (MSFT) reported its fiscal first quarter numbers, and, as Steven Mallas noted, it easily outpaced earnings estimates for the quarter.

Analysts had been expecting to see the company report earnings of 55 cents per share, but actual earnings came in well above at 62 cents per share.

It was a really good quarter for Microsoft, but revenues did not rise enough to stay above Apple's (AAPL) recent quarterly numbers. Microsoft had revenues of $16.2 billion during the quarter, up from $16 billion during its fourth quarter. Apple reported earlier this month it had revenues of $20.34 billion.

The earnings crunch continues this week, and analysts surveyed by Thomson Reuters are anticipating lots of strong quarterly reports.

For example, year-over-year earnings growth from big oil Chevron (CVX), ConocoPhillips (COP), ExxonMobil (XOM) and Royal Dutch Shell (RDS.A) are expected to be in double digits. The same is true of many other energy and mining concerns reporting this week: Allegheny Technologies (ATI), Alliant Energy (LNT), Arch Coal (ACI), Cliffs Natural Resources (CLF), CMS Energy (CMS), CONSOL Energy (CNX), DPL (DPL), Hess Corp. (HES), Minerals Technologies (MTX), Pioneer Natural Resources (PXD), PPL Corp. (PPL), Southwestern Energy (SWN), Total (TOT), Whiting Petroleum (WLL), Williams Companies (WMB) and Wisconsin Energy (WEC).

Microsoft Corp. (NASDAQ:MSFT) will report its first fiscal quarterly earnings after the close today, and the webcast is scheduled for 5:30 p.m. ET.

Investors and analysts will look at three main business segments: Microsoft applications, gaming and the online division.

• After many delays, Microsoft is finally about to launch its new operating system, Windows Vista. Investors are quite bullish on Vista, expecting higher PC sales and higher licensing income as a result. Also, Microsoft's new version of its Office application should be ready next year.
• Xbox 360 - another bullish outlook. Xbox is expected to gain market share in the coming year, mostly from PlayStation. And while Microsoft still loses money on Xbox sales, these losses are expected to diminish and eventually disappear.
• Finally, the online division. Microsoft has rolled out its Live version and the Live search. However, competition here is strong.

Other issues:

• Zune - while most don't expect Microsoft to make significant strides at first, investors are upbeat about the product
• Web 2.0 - what could the impact of online applications do to Microsoft suites of product?
• Cash - investors are eager for Microsoft to do something with its big cash reserve.

As you can see, most of the issues are very forward-looking, indicating investors wouldn't put much emphasis into this quarter's numbers, but will look at the plans and the indications going forward.

In numbers: Consensus for this quarter is for 31 cents earnings per share on $10.8 billion in revenue.

At $28.17, MSFT stock had a good run since June, up over 20%. It is now near its 52-week high.
