Shares of Microsoft were pummeled following a disappointing second quarter, making it TheStreet's Move of the Day. The tech giant reported a drop in quarterly profit to 71 cents a share from 78 cents a year earlier, a result of restructuring efforts. The report unveiled other worrying signs of stalled growth, particularly in its profitable Windows division. Sales of the operating software tumbled 13% over the quarter in both the commercial and consumer sides of the business. Third-quarter guidance also came in a little light with expected sales as high as $21.4 billion expected. Analysts had forecast an average $24 billion.
