How dumb does Microsoft really think the general public are? Of course they will say it only monitors your typing and doesn't log keystrokes, but the simple fact that most of the general public that own Windows 8 started by signing up or signing in to their Microsoft Account. By signing in to your Microsoft account then allows any actions to be monitored through the Microsoft Account Servers. Don't be naive about "big data". If there is a way to claim and record any data, regardless of how important it may or may not be, you can be sure it is being utilized. When you open Windows 8 and the future Windows 10, DO NOT sign in to your Microsoft account and sign in to your local account only!
