If you don't want certain programs or applications to run automatically on startup, there's an easy way to disable them.
  • Click Start
  • Type msconfig in the search box
  • Click Continue in the User Account Control to continue
  • Click on the Startup Tab
  • Uncheck any boxes in the "Startup Items" that you wish to disable or click the Disable All button (not recommended)
  • Click OK
If you need to re-enable any of the programs, go through the same process and check the boxes of programs you wish to run automatically on startup.
