Twenty-four hours after it was released, Windows 10 is being run on more than 14 million devices.
"We’re humbled and grateful to see the response to Windows 10," the company wrote on its Windows blog. "We have seen unprecedented demand for Windows 10, with reviews and customer feedback overwhelmingly positive around the globe."
Microsoft's new operating system comes with Cortana, the digital assistant previously only available on Windows Phone, and a replacement for Internet Explorer called Edge. It provides a middle ground between the touchscreen-focused Windows 8 and the more classic Windows 7. (No, there is no Windows 9).

Windows 10 is available as a free upgrade for users of Windows 7 and 8. For everyone else, it's available for $119 for the consumer version and $199 for the Pro version.
While 14 million devices might seem like a lot, Microsoft said it wants Windows 10 to be on 1 billion devices in "the next few years."
The operating system is first being released to people who signed up to be "Windows Insiders" ahead of time, with others being directed to download the Get Windows 10 app to reserve their own upgrade.
