Thumbnail Previews (Win7 32 & 64) for Non-PDF e-Books

[DJwa163]

Adobe PDF e-Books can have a preview on Windows Seven, if Adobe Reader is installed.

Similar stuff is present in Win7 for a lexicon of filetypes:
Supported file types for thumbnails/previews - ResourceSpace Documentation Wiki

But, unfortunately enough, we still lack a tool/ third-party app to enable thumbnail previews for other filetypes, that we often use in daily life, (for example *.pdb, *.chm, *.epub ebooks etc). Even if, we have a third-party viewer installed for all of them, the thumnail preview never appears (instead, they take up the filetype-icon)

Many Media files can have icons with appropriate players/codecs installed:
FAQ - Thumbnails

But, works need to be done for the e-book sector.
Similar issues have been already addressed here on this forum, so I don't think, our experts can't make it.

Thanks everyone. I am new here, If I've broken any forum rules, please pardon me, and teach me the proper way.

Edit: I found a similar app here:
PreviewConfig 1.1.0.0

But, it has several limitations, including adding new filetypes.
