It sounds then like some of the recomendations of PCPitstop are pure BS?
I don't know about BS, but I just don't believe in miracle tools.
Is cleaning the registry not really necessary?
It is. Dead entries will slow down your computer.
Curious about the page file. Should I lrave it alone, does Windows really know best?
I have it set. I don't like M$ messing around my computer.
How about putting the page file in RAM on a thumb drive?
I don't think so. I even don't believe in putting it on separate partition, since with todays speedy computer, it may save you couple of miliseconds in performance.
I do use McAfee security suite that is FREE with Comcast cable.
If it works for you, and it's free, fine. Personally, I don't like it.
I do de-frag the HD frequently.
It's been under discussion for years, so who really knows. I defrag, but not frequently.
All of it....IMHO.
