System Configuration is a tool that can help identify problems that might prevent Windows from starting correctly. You can start Windows with common services and startup programs turned off and then turn them back on, one at a time. If a problem doesn't occur when a service is turned off, but does occur when that service is turned on, then the service could be the cause of the problem. This tool can be accessed by typing the command msconfig in the Run or Search tab in Windows XP and 7
System Configuration is intended to find and isolate problems, but it's not meant as a startup management program. To permanently remove or turn off programs or services that run at startup, see Uninstall or change a program.
The following table describes the tabs and options that are available in System Configuration:
