How to Run Startup Manager
Many of the programs you install in your computer will try to launch when Windows starts, and each application will consume a part of your computer's available memory. Since almost all of these programs run behind the scenes, they steel your computer resources without your knowledge. Removing these programs from startup will increase boot time and your waiting.
Click "Start," select "Run" in Windows XP, type "msconfig" and hit "Enter. In Windows Vista or Windows 7, click "Start," type "msconfig" in the Search box and hit "Enter."
Click on the "Startup" tab in the System Configuration Utility dialog box to view a list of programs that automatically run during Windows startup. Place a check mark on all programs that you wish to automatically run during startup and remove check marks on programs that you do not wish to automatically run.
Click "Apply" and choose "Close." Restart your computer to allow the new setting to take effect. You can repeat the above procedures to view the list of startup programs again and see if the changes you made are reflected in the list. Your computer should have a faster boot time after making the adjustments.
