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.
Considering their target is 'Experts and IT pros', there is an expected, basic responsibility that lies with the user that A) you understood what you signed up for, B) you wouldn't be stupid enough to do anything private/critical on software released only for testing - its fundamentally insecure.
Its also not clear, when or where keystrokes are logged. Maybe its not a 24/7 thing, but based on specific interaction (windows key combos, etc.) - I don't know. I saw no mention of attempts to view the data captured. Anyone have technical insight?
