Microsoft and Google Earnings Live Blog

NEW YORK (TheStreet) -- Tech heavyweights Microsoft(MSFT) and Google(GOOG) are on deck to report their fourth, and second, quarter results, respectively, after market close, as earnings season clicks into gear.

Microsoft investors will be eager for any additional information on the forthcoming launch of Windows 8. The Redmond, Wash.-based firm announced on Wednesday that the eagerly-anticipated product will be generally available on Oct.26.

Seen as a driver of top-line growth, Windows 8 is expected to be a positive catalyst to the tech giant's financial results toward the end of the year.

Microsoft has also announced that Office 2013 will be available later this year.

Wall Street expects Microsoft to report sales of $18.13 billion and earnings of 62 cents a share.

Google investors will be keen to see the search giant emulate its strong first-quarter results earlier this year.

Analysts surveyed by Thomson Reuters are looking for Google revenue, excluding traffic acquisition costs, of $8.407 billion and earnings of $10.04 a share.

The tech giant's second-quarter results are also its first since clinching its acquisition of Motorola Mobility in May.

Google shares have slipped 7.49% this year. Microsoft's stock is up 18.18% over the same period.

TheStreet will be live-blogging Microsoft and Google's earnings starting at 3.45 PM ET:
