Windows Media Player 11 Shows Thumbnails Only for Certain Files

By default WMP11 (well, any of them really) don't give their logo (icon, .ico) to ALL media formats, ONLY the ones it can play default (meaning, if you install codecs, WMP won't add their logo to that file(s))

Windows Media Player is the default media player set for those formats.

You mean default for those codecs, or default as in the files it plays by default without codecs?

What do you mean by "default for those codecs" ?

I mean all those file types are associated to be opened with Windows Media Player. When I click them, Windows Media Player pops up and plays them.

Here is exactly what I mean.

Here is what my Video folder looks like.

What I mean is those file extensions were added due to the codecs, right?

I find it hard to tell weather the codecs added anything to the list.

I know I associated everything manually and that's all I know for certain. I accessed the "Default Programs" section for the first time ever when I had to take the screen shot I posted. I can only guess what extensions were there before I installed the codecs.

I found an article on Microsoft's website which lists all file formats Windows Media Player associates with by default, codecs or no codecs and when I compared it to the list from "Default Programs", it seems like the extensions from the screen shot I submitted earlier are the default ones and nothing has been added to, or removed from the list.

What you could do is uninstall the codecs, look at your list - make a personal note of what you see, then reinstall, and then you can which are added.

Okay I got it. Seems like 64 bit Explorer can't hook into 32 bit codec dll's in order to generate the thumbs. I launched a 32 bit explorer process and navigated to the Video folder and most of my thumbnails were generated right away.

Still, tell me please, how do I solve this issue in a way that I don't need to use a 32 bit explorer window to generate the thumbs manually.

What do you mean by "32 bit explorer?" ?
