Ever since the release of Windows 3.0, Microsoft has had something like a death grip on the computer industry, closing in on close to 95% market share globally. Today, they’re still hugely successful in the computer market and completely dominate it, but the total market share for Windows has, for the first time in its history, dropped below 90%. The slippage began with the release of Windows Vista, and further dropped with Windows 8, with more users buying into Apple’s products like OS X and the Mac family, or migrating to Linux. While the slight drop below 90% isn’t anywhere close to a crisis for Microsoft, it is an indication that the wheels are slowly turning, and their customers are looking at alternatives more than ever before.
Windows 7 also drops below 50% market share for the first time, possibly signaling that more people are allowing that Windows 10 upgrade through on their machines. Windows XP and Windows 2000 also see a usage drop, but these OSes are still around primarily for industrial applications, and they’ll likely stay there for a very long time. Apple, meanwhile, is close to 10% in global desktop PC market share, with around 3.28% hidden in the “Other” category primarily composed of machines running OS X 10.9 and older.
