My sister has a new computer, it has Vista. She has had it for only three weeks and it has started to run so very slow. I know that she has not had it long enough for it to need a complete cleaning, the registry cleaner I mean, but why else would it be so slow? I have been looking it up online and it seems to me that it is the problem, but I still cannot believe that it has gotten so much on it in such a short time. I wonder if she will need a Vista registry cleaner?
