How to Manage Startup Applications in Windows 8@ 2013/05/10
Windows 8 now includes an interface for managing startup applications in a location that makes more sense: the new, improved Task Manager. This makes it easier to specify which startup applications can start with Windows and use your system resources.
NOTE: Managing startup applications only applies to desktop applications. Modern UI (Metro) Windows 8 apps are not allowed to start automatically when Windows starts.
There are several ways of accessing the Task Manager in Windows 8. One method is to right-click on the Taskbar and select Task Manager from the popup window.
