Map a drive to a network share that contains several sub-folders that contains images files or PDFs
Open an Explorer window and navigate to the parent folder.
Attempt to rename each folder successively, while drilling into the sub-folder contents.
Continue step 3 until an error dialog containing the following text appears indicating that the sub-folder cannot be renamed:
"The action can't be completed because the folder or a file in it is open in another program. Close the file or folder and try again."
The folder rename operation fails because thumbcache.dll still has an open handle to the local thumbs.db file and does not currently implement a mechanism to release the handle to the file in a more dynamic and timely fashion.
To work around the issue, enable User Group Policy setting for "Turn off the caching of thumbnails in hidden thumbs.db files":
User Configuration\Administrative Templates\Windows Components\Windows Explorer
"Turn off the caching of thumbnails in hidden thumbs.db files"

To have us edit the registry folders for you, go to the "Fix it for me" section. If you prefer to fix this problem yourself, go to the "Let me fix it myself" section.
Another workaround is to wait approximately 1-5 minutes then retry the rename operation.
