Disable unnecessary startup programs

When you turn on your PC, some programs start automatically and run in the background. You can disable these programs, so they don’t run when your PC starts up.

1. Many programs are designed to start automatically when Windows starts. Software manufacturers often set their programs to open in the background, so you don’t see them running, but so they'll open quickly when you go to use them. This is helpful for programs you use a lot, but not for programs you don’t use often because it slows down the time it takes Windows to start.
2. Find the programs that start automatically
3. Sometimes you can figure out which programs start automatically by looking at the program icons in the notification area that’s on the far right of the taskbar. Check there first to see if there are any programs running that you don’t want to start automatically. To try to find out the name of the program, point to the icon with your mouse pointer. Make sure you select Show hidden icons , so you don’t miss any programs.
