On Windows Vista, when browsing to a network folder containing executables, Windows Explorer seems to load all the files completely just to be able to show the executable icon (the resource monitor indicates loads of traffic during the loading of the directory) On XP only a part of the file is loaded. Is there a way to avoid the complete loading of these files? Note that disabling my anti virus does not help. Update: This only happens with for executable linked with /SWAPRUN:NET. Microsoft confirmed this as a bug in Vista, but they seem not very eager to fix this.
