Microsoft (NASDAQ: MSFT) has been "almost eerily silent" about the early success of Windows 7, writes Ed Bott at ZDNet, even though it has already sold 175 million licenses for it. It comes as no surprise that Vista users were eager to make the switch, but XP users are upgrading in significant numbers as well, Bott reports.

Bott writes that evidence suggests that companies are moving to the latest OS much more quickly than they moved to Vista in 2007-2008 or to XP in 2002-2003. "In fact, it's good enough to finally dislodge XP's stranglehold on corporate computing," Bott writes of Windows 7. Approximately 70-75 percent of corporate desktop PCs run XP today, but if the current Windows 7 adoption rate persists, the new OS will probably pass XP by 2012, according to Bott's calculations.

The lack of chest-thumping out of Microsoft demonstrates the company's "marketing ineptitude," writes Devindra Hardawar in a post at VentureBeat. "Now that Microsoft actually has a legitimate success on its hands, it doesn't quite know how to sell it."
