I am curious if there is a way to see thumbnails for more than the default file types (i.e. GIF, JPG, BMP, PNG) in Windows 7. I tend to use other formats like DNG, CRW, CR2, TIFF, etc., and sadly, Windows does not support thumbnail previews of these images by default.
I used to use a few registry hacks in previous version of windows, however they no longer seem to work for Vista/7. I currently run Windows 7 64bit.
