Video preview thumbnails

Hello,

System file corruption is one of the possible reasons why thumbnail preview has recently disappeared. To better assist you, please answer the following:

• For clarification, are referring to video preview thumbnails when using File Explorer?
  
• We would like to verify if you are referring to the Fall Creators Update. To see your
  Windows build and version, please follow the steps in this
  article.
  

In the meantime, we suggest creating a Test User Profile. This is to see if the same issue occurs on a different user profile.

To create a Test User Profile, follow these steps:

• On Search, type Settings then hit the
  Enter key.
• On Settings window, select Accounts.
• Select Family & other people.
  
• Select Add someone else to this PC.
• Name the User Profile as TEST.
• Assign a password for TEST user, then select Next.
• Sign in TEST user.

We'll be waiting on the results.
