Downloaded and used this ap based on Gizmo's newsletter, where it was rated nicely. Had been having problems with slow response on my laptop, even though I've been running lots of other spyware apps etc.
Found lots of problem areas that were fixed, system is now up and running like it's new again.
There is a paid-for version that has more options, but this one works for me. Also using the IoBit smart defrag, works nicely also.
