Windows 10 passes 25% market share, Vista drops below 1%

A year and a half after its release, Windows 10 has passed 25 percent market share. That means one in four computers are now running the latest and greatest operating system from Microsoft, according to Net Applications.

Windows 10 was installed on over 75 million PCs in its first four weeks, passed 110 million devices after 10 weeks, 200 million in under six months, 270 million after eight months, 300 million after nine months, 350 million after 11 months, and 400 million after 14 months. Microsoft was aiming for 1 billion devices running Windows 10 “in two to three years,” but backpedaled on that goal.
