Windows Explorer's Large or Extra-large icons views will show a preview image of the last active graph before the project file was saved.
If you don’t see the preview image in Windows Explorer, please first make sure Always show icons, never thumbnails checkbox is unchecked in the Folder Options dialog (by menu File: Options)
If Always show icons, never thumbnails is unchecked, please try to register OPJHandler.dll as follow:
regsvr32 "<Origin Program Folder>\OPJHandlers.dll"
For example, if you installed Origin 2023 in the default path, you can type
regsvr32 "C:\Program Files\OriginLab\Origin2023\OPJHandlers.dll"
If the preview image is still not shown after trying above solution, please check if an anti-virus software blocks OPJHandler.dll, like Kaspersky.
