This is up from 300 million in May and 270 million in March. At one time, Microsoft said Windows 10 was on the "fastest growth trajectory of any versions of Windows ever." However, it remains to be seen if this continues to be true. Whatever the case, Microsoft's 350 million figure counts installs across all Windows 10 devices, including PC, Xbox One, and phones.
However, it's unclear how Microsoft measured satisfaction, and not everyone has been thrilled with Microsoft's efforts to encourage them to upgrade to Windows 10. One woman sued the company over an unwanted upgrade and ended up receiving a $10,000 reward from Microsoft. That was of course an extreme circumstance and far from the norm, however.
Additionally, engagement levels for Windows 10 have been "incredible," Mehdi said. Since Window 10 launched last summer, people have spent more than 135 billion hours on it.
"We're pleased that so many of you are being more productive and having more fun with Windows 10," he said. "Your feedback has been a key input into the design of the Anniversary Update."

In other Windows 10 news, Microsoft's free upgrade offer--which is available to select Windows 7 and Windows 8 users--is good until July 29.
