Windows Light and Dark Theme
Enable Use Windows light/dark theme (applies on restart) on the About tab to make PDMPublisher use the Windows app theme detected when SOLIDWORKS starts.

Restart SOLIDWORKS after changing the option. The current task pane does not switch themes immediately.
When the option is disabled, PDMPublisher uses its original light appearance.
Note
Theme synchronization changes colors only. It does not change profiles, settings, exported files, or publishing behavior.
