Every program that runs when you start your Windows 7 computer slows it down; worse, in many cases there is no need for these programs to run during start-up. To significantly speed up your computer, you can stop these programs from starting at start-up. There are three places you need to look when locating start-up programs: The Start Menu, Windows Configuration and the programs themselves. Although the former two options can disable all start-up programs, if the program itself is configured to run at start-up it may re-enable itself.
Click the "Start" button, "All Programs" and "Startup." Right-click any program in the "Startup" folder and select "Delete" to remove it from the Startup folder. This keeps that program from running at start-up.
Hold the "Windows" key and press "R" to open the "Run" window. Type "msconfig" and press "Enter." Click the "Startup" tab and uncheck any start-up program you don't want to run during start-up. Click "OK." You can then choose to restart your computer immediately or later.
Open the program you wish to disable from running at start-up. Look for its "Options" or "Preferences." Browse through these options for an option to "Run Program at Startup." Disable this feature to keep the program from re-enabling itself.
