Ballmer this week won the approval of 92 percent of shareholders, earning a total of 5.4 billion votes in favor and 468 million votes against, according to a Form 8-K that Microsoft filed Thursday with the Securities and Exchange Commission, outlining the election of its board of directors. Although that's an overwhelming majority for Ballmer, it's down from the 95 percent approval from shareholders last year. Over the last several years, shareholders have been expressing their dissatisfaction with Ballmer over a host of issues, including the company's static stock price. In addition, the board in October outlined some of the issues it has with Ballmer, saying that "lower than expected initial sales of Windows Phone 7," along with a 2 percent decline in Windows and Windows Live Division revenue, held it back from giving the Microsoft CEO his full bonus on the year.
