When viewing a folder of images in "Large Icons" mode, I often see the thumbnails slowly regenerate. How do I permanently store those thumbnails so I don't have to wait ages whenever I open a folder? I'm using Windows Vista Business 64-bit.
This is a good article about enabling and disabling thumbnail caching in several ways, also explaining why you may not want to have it enabled. You can change the default behavior by either a registry or a policy change.
