Windows 7 To Support Popular Video Formats
The hunt for the codec is one that many Windows users know. Windows right out of the box supported only a handful of codecs and it always required the installation of addition audio and video codecs to make many of the videos on the Internet playable. This changed a bit with the spreading of so video players that would make use of binary codecs that did not require system wide codecs to be installed. Still; Users with little knowledge where perplexed when Windows could not play a codec and they usually resorted to downloading a codec package that installed the one codec needed next to dozens that were not needed at all.
Windows 7 is about to change that: The new operating system will come bundled with codecs that can play Divx, Xvid, H.264, AAC and a handful of other popular formats which means that one of the major restrictions of Windows has been removed.

This is interesting for users who plan on using the new libraries functionality or Microsoft tools that index files on the computer because it is likely that these new formats will be included in the indexing routines. This means that users do not have to rely on third party applications anymore to play, search or manage those multimedia files.
Long mentioned that Microsoft has added transcoding possibilities right into the Windows Shell which means that a multimedia file could be easily transcoded during the transfer from one device to another.
With this new pool of decoders and encoders, Microsoft’s also doing some building in some interesting transcoding (decoding and re-encoding from one format to another) technology in Windows. From what I can at least gather from the presentation, transcoding is actually built right into the Windows 7 shell. That is, if you drag and drop a video from your desktop to your portable media player, the conversion will happen automatically. Personally, anything that removes unnecessary third-party bloatware to add content to portable devices gets my vote.
You can download the full WinHec PowerPoint presentation where the announcement has been made. Keep in mind that it is coming in the pptx format which only the newest version of PowerPoint can read.
But there’s an even simpler solution than downloading codecs: VLC player.
.mkv, .mka and .mks files aren’t there either, I think.
But… VLC media player sucks.
Download the Vista Codec Pack from shark007.net and play EVERYTHING in windows media player

Agreed, even with VLC, half the files I have don’t work. Shark’s codec pack worked wonders on my computer. If codec packs are not your thing, another option is GOM player, much better than VLC..
This makes it easyer 4 the hope user to get some files working.. good addition but i will still need a codex pack for MKV and others
I hope this makes it in windows 7, i don’t like having too many media players and some plugins for media players dont reproduce non-native video properly and prevent you from seeking the video.
