What happened to Windows Security Center?

Action Center replaces Windows Security Center in this version of Windows.

Action Center manages firewall settings, Windows Update, antispyware software settings,
Internet security, and User Account control settings. Action Center also monitors computer
maintenance settings and provides links to troubleshooters and other tools that can
help fix problems.

Open Action Center by clicking the Start button , clicking Control Panel, and then, 
under System and Security, clicking Review your computer's status.
