What happened?
To kick off the new year, Microsoft (MSFT -1.41%) has just announced that Windows 10 is now active on over 200 million devices. Marketing exec Yusuf Mehdi also shared a few other notable stats on the official Windows blog. The software giant had a big Black Friday, with 40% of new device activations becoming active since then.

Windows 10 is on track to be the fastest-adopted version of Windows ever. Windows 10 is also doing well in the enterprise and education markets, with 76% of Microsoft's enterprise customers piloting the new version. There are now over 22 million Windows 10 devices being used by enterprise and education customers.

Does it matter?
It goes without saying that Windows 10 adoption is incredibly important to Microsoft's business, particularly as the company continues to transition the revenue model to Windows-as-a-Service. Microsoft continues to make progress toward its goal of having Windows 10 on 1 billion devices.

Mehdi made a similar announcement last August when Windows 10 reached 75 million devices, which was soon followed by a third-party estimate of 100 million devices the following month. Microsoft has been enjoying a solid run under Satya Nadella, as the new CEO is executing on a different long-term vision than his predecessor.
