Windows Explorer on my wife's computer (running W7 Home Premium and completely up to date with Windows Updates) takes 4 or 5 minutes to finish running right after a power-up boot. The hourglass icon seems to sit there forever, but the folders and files finally appear. Later, when running an Explorer-type function, such as saving a file in Word or opening a file in some other application, a long delay occurs again. Her computer hardware and software components are very similar to mine, and I never have this problem. She may have a few hundred more photo files than I have, but I can't identify any significant difference. During these long delays I've watched the Task Manager, and no appreciable amount of processor time is being used. Is there something I can monitor or log to find out where this time is being spent?
