Sorry, but this software works poorly with Windows XP (1 gHz Pentium3, 512 mb RAM). Copying a CD, it trashes the blank nearly half the time, even at 2X speed, nothing else running. If CD has 9 tracks or more, it reads 9th and succeeding tracks about 1/4 speed. I defrag often. Upgrades are of no help. Poor customer support. Also had trouble when using Windows me. Review of their web site shows other customers having many problems also; fixes often not available even for persisting problems.
