Preview Pane is Blank for Every File Type Except Images

We’ve seen the “No preview available” situations before, caused by the incorrect or missing preview handler registration for a file type. Here is a similar problem: the preview pane is empty, showing just the white space for all file types except images.

However, the image file types may preview correctly.

The above issue happens due to a missing Preview Handler Surrogate Host registration.


To resolve the issue, download prevhost.reg and run it.

INFO: Contents of the REG file

Windows Registry Editor Version 5.00

@="Preview Handler Surrogate Host"

(The above fix applies to all versions of Windows 10 and 11. Last tested in 22H2.)

I hope that helps. Let’s know your comments.
