Windows 10 hits 75 million devices in less than a month

You can't get to one billion devices without hitting 75 million first

Just a month after its release, Windows 10 has been installed on 75 million computers — well on its way to Microsoft's goal of eventually hitting one billion different devices, according to a tweetstorm on Wednesday by Microsoft VP of Windows and Devices Yusif Mehdi.

Windows 10 had momentum from the start. It reached 14 million users just 24 hours after its release in late July. These healthy numbers could mean Microsoft's strategy of making the operating system free to Windows 7 and 8 users is working.
