--- Comment #3 from V Stuart Foote <vstuart.foote@utsa.edu> ---
Yes, I marked it invalid in error. More likely it ends up a WONTFIX. But with
needed refactoring for bug 127433 to support Windows Dark mode, may be of dev
interest to implement.

Windows shell integration is provided in core/win32/shlxthdl where ooofilt
provides the current ability to search within ODF documents. 

While one page 'preview' thumbnails are provided by a dedicated
shlxthdl/thumbviewer that extracts a document preview if recorded into the ODF
archive and makes it available to the Windows shell (needs refactoring for bug
127433).

Though LibreOffice provides a search/find capability, there is no LibreOffice
provided preview of ODF in the Windows Explorer 'Preview Pane' as implemented
at Windows Vista for visual browsing of documents in Windows Explorer. [1]

Preview Handlers get recorded to Windows registry in
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers and linked by
file extension.

When installed, Microsoft Office (365, 2016) provides a Preview Handler
implementation for browsing OOXML formatted documents and for some ODF
formats--but these are not LibreOffice's ODF renderings.

No, at that point in the BZ issue that discussion was only about the Microsoft
Office provided 'Preview Handler' not previewing AOO documents. Seems no longer
an issue with Office 365 or Office 2016 installed.

Please provide links for threads/blogs expressing rational use case, always
helpful to document requirements.
