Say what you want about Microsoft and Windows; it is as familiar as an old shoe, it gets the job done, and Microsoft is always making it better. I found the latest improvement quite by accident, and it is very handy already. One of the best ways to change the configuration, or streamline the boot-up process for XP is to run the handy "msconfig" command. Just click the Start button, then run, and type "msconfig" in the box.
A handy dandy dialog box pops up that permits the user to monitor the Startup programs and to delete the ones you don't need, significantly reducing memory use, and making boot up faster. There are other boxes, which permit modification of the initialization files that load when XP starts. Well, when I loaded up "msconfig" recently to remove a useless program that was loading at startup, I found a new tab, identified as Tools, that, when clicked, brings up a laundry list of useful tasks that can be performed in XP. Try it, you'll like it.
