Did a quick search. This seems to be saved in “ShowPreviewHandlers” in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced. This could be added to the Bug Report Tool.I guess we need some change here to add a mention that the File Explorer > Options > View > “Show preview handlers in preview pane” option needs to be checked:

@crutkas
I didn’t even know that was a thing! Solid find!
We should see if we can’t detect this.
I mean this:
Module won’t work if this is off.
@crutkas Why not try to automatically change this setting’s registry key to
1while preview feature enabled? I have tested it and it looks effective immediately.We should have this to a FAQ
