The preview for videos shows only the first selected video in the preview pane.
This is a bug with Windows Media Player on Windows 10.
The issue can be fixed by enabling preview_release_handler_on_clear:
- In Everything, type in the following search and press ENTER:
/preview_release_handler_on_clear=1
Note: When this option is enabled, playing a video in the preview pane will cause the next selected item to not display correctly. Also a bug with Windows Media Player. Reselecting the item will fix the issue.
