Windows 7 Thumbnails of videos not showing

[Aasima]

Greetings. I have a problem with the display of thumbnails of videos, especially AVIs and MPGs. Apparently mkv, 3gp and mp4 display fine. I have attached an example of what's showing.

Welcome to the forums.

There are many fixes for this - depending on the source of the problem (eg: mem issues, settings, codecs, cache, etc).

You can try to install the Redistributable Package:
(x86): http://www.microsoft.com/en-us/download/details.aspx?id=5555
(x64): Download Microsoft Visual C++ 2010 Redistributable Package (x64) from Official Microsoft Download Center

Or you can try various settings and codecs fixes:

There are other solutions so if it's still not fixed after trying the above, get back and we will post more specific solutions.
