Microsoft has revealed details about the data it is tracking via its new operating system (OS), Windows 10.
In a blog, the firm listed statistics on how many minutes had been spent by users in total in the Edge browser and the number of photographs which had been viewed in the Photo app.
The firm also said that Windows 10 was now active on over 200 million devices.
However, some people have questioned whether the data tracking is a threat to privacy.
Since Windows 10 was launched, Microsoft has been tracking information about how those with the OS are using it.
Until now though, relatively little has been known about what data is being collected.
"Microsoft is deeply committed to protecting our customers' privacy," a spokesman for the company told the BBC.
