What operating system?
It's part of windows. Same as if you went to Start > Run, and typed in "msconfig" (without quotes).
If you changed something in MSCONFIG, then the System Configuration Utility appears upon startup until you tell Windows that you wish to accept the changes and not to remind you that MSCONFIG has been changed.
System Configuration Utility...any ideas why this happens and how can I stop it from appearing each time I turn on my pc?
