Microsoft (MSFT) has not changed much since 2000, since Steve Ballmer replaced Bill Gates. But the same could be said for a lot of stocks during the 2000 - 2010 era. The Dow is only slightly higher during the same time, peaking near 12,000 in 2000 and now being at 13,350.
Operating Systems ((OS)) are the core business of Microsoft, although they have now expanded into hundreds of niche industries from making keyboards, video games and business applications.
