I am using Windows 7 from past few months. I am really satisfied with the feature of this program. Well now my question is how I can create thumbnails of Windows Meta File (.wmf). I can see the .wmf file by simply clicking on it but there is no thumbnail is produced for the same. As far as I know Windows 7 is able to create thumbnail for the other clip art formats but unable to do so for .wmf formats. Even it was happening in to Windows XP. Any help will be highly appreciated. Thanks in advance.
