Fixed this already, but just a FYI as Google doesn't have this listed:
This appears in the Metro Control Panel under Users after I tried adding an Exchange account to the Mail app, and acknowledged the following security-related dialog without thinking.
With that setting enabled, your PC will lock itself after dimming the screen or after waking it from sleep - your Power Options settings have no effect here. Having your PC prompt you for your password after waking up or idling isn't particularly helpful if you're on a single user desktop at home.
Disabling it is simple but not particularly straight forward at first: go to the desktop Control Panel, User Accounts, and click "Reset Security Policies" on the left. That should do the trick.
