Microsoft said that "on the heels of momentum shared last month at Build, Microsoft is thrilled to share that Windows 10 is now running on 300 million active devices around the world. We’re also seeing significant growth in people using the awesome features in Windows 10, taking advantage of Microsoft Edge, Cortana, PC gaming, apps and the Windows Store more than ever before."
"With our customer’s support, Windows 10 has become the fastest adopted version of Windows in history. Microsoft wants everyone to enjoy the myriad benefits that come with Windows 10, which is why they encourage everyone who has yet to take advantage of the free upgrade offer to do so now, as it will end on July 29."
