On NT, do you ever wonder why Performance Monitor starts up blank on some computers, and others have process monitored automatically upon start up? Well, Performance Monitor first looks for a file called _default.pmc in the startup directory and will use this as its settings if it finds the file. If it can’t find the file, it starts up blank. Note that, as with most applications, you can create a shortcut and pass Performance Monitor a .pmc file to start with, so you can create multiple scenario monitors (.pmc files) and start them via a shortcut as needed.
