Windows thumbnail cache size

Recently I had the problem because windows is not able to cache the thumbnails for a folder with a hugh size of pictures. I found some registry values which helps me to increase this size.

The following RegEdit script will change the “Max Cached Icons” from 512 to 4095. I tested it with windows 7 and it works for pictures and movies. Just copy/paste it to a file called “thumbnail_cache.reg” and execute it with a double click on it.
