Description

This policy setting allows you to turn off caching of thumbnail pictures. If you enable this policy setting, thumbnail views are not cached. If you disable or do not configure this policy setting, thumbnail views are cached. Note: For shared corporate workstations or computers where security is a top concern, you should enable this policy setting to turn off the thumbnail view cache, because the thumbnail cache can be read by everyone.
