Upgraded about a week ago and things have gone fairly well so far, but I just noticed something that really bothers me. The thumbnails for video files are not working. The folder option of show icon never thumbnail is not checked, and in system performance show thumbnail instead of icon is checked....folder option set to "video" type (but same thing happens with other types). I understand that those settings are normally the cause of the this type of issue, but not this time. Photo thumbnails work just fine. It may seem minor but it's a deal killer for me and I will wipe the drive and go back to windows 7 if this is just the way it works. However I'm thinking it must be something I can correct because they couldn't possibly have gotten rid of video thumbnails. Any ideas are appreciated.
