My husband was using my laptop the other day.  He noticed that it had a slow vista startup problem. After he looked through my computer’s registry, he said that it was full of things that weren’t needed, that’s why my computer was starting so slowly. He told me that if it got cleaned, my computer would go a lot faster.  He told me that it was too precise a job for him to try to do himself, so he downloaded a program that would clean it up and get rid of all the extraneous stuff.  It starts so much faster now.
