After a clean install of win7 (x64), the start menu icons never (or take extremely long) to load the first time after opening them. This primarily happens at Start button > All programs (and the folders within all programs). After the first time, they load normally. This happens each time I restart my computer. The memory isn't a problem as I have 4gb of it. The icons/thumbnails of all my other programs/pictures appears to be fine too. Any help please?
