I recently went from vista to win 7 and have now found I can't backup my files. I'm not sure how to go about fixing the problem, as I'm not fully competent with computers so any help would be grateful. When I try to backup files i get a message saying I can't with the code 0x80040154. I also noticed I don't have the search function any more when you click start, unless that has been removed on win 7.
