ETA: OMG. marith is totally a hero of the revolution. She has told me about MSCONFIG and sysinfo.org and I have at least gotten the WinXPDisable thing turned off and am going through the task manager to figure out what unnecessary shit is running on my computer and TURNING IT OFF. All hail Marith! Huzzah! Huzzah! Huzzah!
