So when I rebooted my computer when I woke up this morning, some of my videos in my videos library changed thumbnails. Is it normal for my videos to do this or no?
 

Solution
If you installed a new video codec which has registered a thumbnail renderer extension for explorer to render thumbnails it is very possible this could happen. Also your thumbs.db file(s) could be corrupted. (You can delete them manually, or use a program such as Link Removed to remove them)
