On Tuesday, Microsoft ( MSFT 0.22% ) will release its quarterly report, and shareholders have seen the stock's price soar to levels not seen since the end of the tech boom in the early 2000s. As much as Microsoft has worked hard to answer competitive pressure from Apple ( AAPL 4.24% ) and other major tech players in the hot areas of mobile devices and cloud computing, the company still has a huge presence in the aging PC market. Although many left that market for dead, recent results from Intel ( INTC 0.94% ) show that a near-term resurgence in the PC industry could help drive growth for Microsoft and other companies with a major PC presence.
