Other versions of Windows are barely relevant. Windows 8.1 has a share of 4.51 percent in December 2018, while Windows XP is still used by 4.54 percent of users. Meanwhile, Windows continues to dominate the ecosystem: 86.20 percent of all users rely on one of Microsoft's operating systems. The rest of the market share different versions of Apple's MacOS at 10.65 percent and Linux distributions at 2.78 percent. Very low proportions hold ChromeOS and BSD.
