Can I just say to anyone who is getting, or just got a machine with Vista installed (and i could be showing myself up badly here!) Don't mess about with the registry, or backup files! I have just half killed my laptop by deciding to clear out unwanted files, as i had hardly any room left. Sadly i deleted stuff that i should have never touched. Now it has to be completely re- installed. I am sure i am going to be villified here, but not all of us are as competent as many of the members on this forum, sorry , i should have asked your advice. I felt so confident, and now i feel so daft! In future i will ask you lot first!
