Microsoft admits Windows 10 preview has a keylogger

Microsoft has admitted that the new Windows 10 operating system tracks keystrokes and examines audio input. The new operating system, currently a free download for users with Windows 7 and Windows 8 licences, not only tracks how long it takes to open different types of files, the make and model of device you're using, but it's also logging keystrokes and collecting voice recordings. Microsoft will not delete data already collected from Windows 10 users.
