Windows Explorer uses BinThumbnail to generate thumbnails for SNES 4 bpp .bin graphics files.
Run install.cmd (with BinThumbnail.dll in the same directory)
Open Windows Explorer (explorer.exe) and navigate to a directory containing SNES 4 bpp .bin files (e.g. ExGraphics/)
Windows Explorer shows icons for the .bin files rendered with SMW palette $A
.bin files contain no metadata, so the thumbnails are always generated assuming 4 bpp
.bin files contain no palette information, so the thumbnails are always generated with SMW palette $A
Does not work in processes run "As Administrator"

I found the tool very simple and straightforward to install. I think an interesting improvement would be allow to use set up a custom palette, maybe by having a palette file in same directory as the DLL file. Still, it makes way easier to look for 4BPP graphics specially on a big SMW hack project.
Important notes for anyone interested in using the tool:
1. Make sure to install on a directory that you don't have plans in moving it to another location. If the DLL gets moved to another path, the preview will stop working and you will have to install it again. The same applies for folders that you might end up deleting it.
2. On my tests, immediately after hitting install.cmd the preview started working on my Windows 10 OS. However, in case you don't see any immediate effect, consider restarting your computer before looking at any .bin file on Windows Explorer.
