The only good thing I can say about this software is that it appears to have a decent "undo" feature, called "Rescue Center." I ran it, and immediately saw the kind of speed improvement I hoped to get from running the program.... which is to say that the previous state of the machine wasn't all that bad in comparison to what it was after the software did its thing. I uninstalled it (and am hoping that the uninstall really was complete as it says). Bye bye!
Now if only I had back the many hours of lost time wasted on this bitter, unpleasant lesson.
My poor old Dell Dimension 4600 has been in semi-retirement since 2009. Doesn't do much but serve files for the Macs in our home. I've downloaded the XP Service paks (and other Microsoft auto-updates) and kept the McAfee anti-virus up-to-date, there are a couple of PC-only programs I need and those get run once or twice a month. I've run a couple of other "tune-up" type programs in the last couple of years, and had no particular problems.
