Many applications install themselves so they start automatically when Windows XP starts. The more programs that try to start simultaneously with the operating system, the longer it takes for the system to boot. There are three ways to change which programs start when Windows does. The first is by deleting the application's startup link in Start, Programs and Startup. Most startup programs are listed in this folder.
The second option is to uncheck startup applications by using the msconfig tool. The final option involves checking the options within individual applications. In the future, check for startup options during the installation process to prevent this problem.
