I consider myself an advanced noob, I know just enough to get into trouble.
I first tried Power Tools and it seemed way over my head, for advanced users who know what they are doinglite
With the lite version, yes, you do have to think a bit, but you can always get things back to the way it was by restoring the back up. It is kind of by trial and error though. I don't think there is any program that is idiot proof. Ccleaner is close, but not as effective, IMO.
I still keep Ccleaner on board because it has support for Opera and a few other features.
I would like to see a registry compactor and a start up program manager for PT Lite as additional features in the future, but I doubt this will happen as this is not a "money' program. It works pretty good as is though. Remove programs would be nice too, but I know this is asking waay too much.
Bottom line: PT Lite in a nice little program, good work.
