The issue you're experiencing with icons and thumbnails disappearing seems to be related to the settings in Windows Explorer. When the option "Always show icons, never thumbnails" is enabled, it indeed prevents thumbnails from displaying, which can affect applications like Word that rely on thumbnail previews. Conversely, if this option is not enabled, it can lead to graphic-type icons disappearing in folders due to potential conflicts or settings in the system.
To resolve this, you can try the following steps:
- Check Folder Options: Ensure that the setting for thumbnails is configured correctly. Go to Control Panel > Appearance and Personalization > Folder Options > View tab, and make sure that "Always show icons, never thumbnails" is not checked.
- Clear Thumbnail Cache: Sometimes, clearing the thumbnail cache can help. You can do this by going to Disk Cleanup and selecting the option to clear thumbnails.
- Adjust Hardware Acceleration: Reducing hardware acceleration may help with display issues in Word. You can follow the workaround mentioned in the context to adjust the settings.
- Registry Check: If you're comfortable with it, checking the registry settings related to icon handling might provide insights. Ensure that the
IconHandlersubkey values are set correctly as per the guidelines provided in the context.
If the problem persists, it might be worth exploring if there are any interactions with the .apk files you mentioned, as running such files on a PC can sometimes lead to unexpected behavior in the operating system.
