Programs ranging from auto-updaters to utilities run automatically every time you turn on your PC, and many of them remain running in the background all day. Although designed for convenience, auto-starting programs also make your computer take longer to boot and can fill your taskbar tray with icons. Rather than waste time quitting unwanted programs every time you reboot, stop applications from loading using the Task Manager in Windows 8 or Msconfig in Windows 7.
Press "Ctrl-Shift-Esc" or right-click the taskbar and choose "Task Manager."

Open the "Startup" tab and uncheck any programs that you want to prevent running automatically. The Command column shows the location of a program to help you identify its purpose.

Click "OK" and choose whether you want to reboot immediately. If you choose "Exit Without Restart," your choices take effect the next time you reboot or turn your computer off and on.
