While in Windows 10 modern style Setting App allows you to access and modify most of the settings options that you may need frequently. Though Control Panel is still there, but starting from un-installing an Applications (including Desktop Apps), Power Management, Setting Up your Internet Connectivity and Firewall everything can be accessed from Setting Windows App.
