Island Dog:I don't use the registry cleaner part of it. I did a few times and it really messed up some associations especially with Microsoft Office.
I, on the other hand, haven't had any problems... so, YMMV. Basically, I think that it comes down to, "If you don't
really know what you're doing, don't mess with Reg stuff." This is especially true when something is hit and miss like this.
But for cleaning random crap off your machine? Heck yeah, this is awesome!
