16-bit BW TIFF thumbnail support

[Vlastimil]

I am looking for any "replacement" for default Windows XP fax and picture viewer (shimgvw.dll) that can't handle 16-bit BW TIFF.

I see there is SageThumbs and XnView Shell Extension:
SageThumbs can create thumbnail inside Windows file explorer but can't display 16-bit BW images (only black thumbnails).
XnView Shell Extension can display 16-bit BW tiff picture thumbnails but only in the context menu.

Is there any way how to see thumbnails for 16-bit BW tiff images inside Windows file explorer?
