Adjust privacy settings - Windows 8

Customize your privacy settings to your liking.
A lot of apps tap into very personal information by default. Indeed, your pictures, location, and name are liberally woven throughout the system, and like many users you may not be comfortable trusting your machine with that much sensitive data. To adjust the settings, press the Windows key + I, and go to Change PC Settings. Select the Privacy option, and personalize the settings for your personal data there.
