Don’t need a thumbnail cache (thumbs.db) on Windows 7 or Windows 8? Disable it.

Windows 7 creates the thumbs.db for a reason. They are very useful and speed up your Windows explorer, because it caches the pictures Windows uses for some folders, instead of generating them over and over again and wasting resources.

However, caching the thumbnails also costs resources, so you might want to disable it.
