However, it could be possible that the thumbnails don’t show up due to a third-party program that you recently installed on your PC. You can simply uninstall the program and check if it helps fix the issue. At the same time, many Windows issues arise due to outdated graphics drivers and hence, you can consider updating the graphics drive and it may well fix the thumbnail issue.

You may also check if there are any video codecs missing that are responsible for not just the malfunctioning of the video files, but also the thumbnails. In such cases, make sure you install the required codecs and this should get the thumbnails back.

Moreover, based on the experience of some users, the thumbnails not showing issue could also be due to the fact that the IconCodecService.dll service is disabled. According to users, this dll service may be responsible for converting PNG to BNP icons and disabling this dll file, may interefere with the thumbnails. Hence, make sure that this service is enabled.

On the other hand, the thumbnails may also disappear due to the Paint Shop Pro program and this issue mainly arises when you are using its 32-bit version. Therefore, make sure that you install both the 32-bit and 64-bit versions of the Paint Shop Pro and you should see the thumbnails back again.

However, a lot of times, many Windows issue could simply arise if your system is affected with a malware. So, you can simply run an antivirus scan and check for any malware and quarantine if any found. This may help you fix the thumbnail issue.

If all fails, you can try a third-party thumbnail generator tool that are easily available online and generate a thumbnail for the affected file or folder.
