Let Windows 7 re-support the preview playback skills in the folder

The Windows 7 system is being recognized by more individuals and business users, and it is constantly being explored by enthusiast testers to explore his features. As the system is relatively new, some of the functions and optimization settings are not discovered by the majority of users. Here, for the initial users of Windows 7, I summarized the skills that are not known to everyone, and I hope to help the beginners.< Br>

Attentive Windows 7 users may find a situation where a newly installed, pure Windows 7 system can preview (partially) AVI, etc. directly in a folder in the library or explorer mode, Windows Media Video files directly supported by Player 12.

But after the user installed Storm Video, Thunder and other third-party "all-round player", those video files that could be previewed and played can only be previewed to one image, but Cannot play directly in the folder.

When I first discovered this problem, I always thought it was caused by compatibility problems between Windows 7 and the player. When trying to solve some problems, the author found a situation: video files including RMVB, VOB and other formats, Windows 7 is always unable to directly preview playback, and Windows Media Player 12 can be played directly (ie no download required) The file of the decoder's video file is only previewed after the third-party player is installed.

After several trials and tests, I confirmed that this is caused by the type restriction that Windows 7 supports for the default file format of video. At present, Microsoft officially only supports the AVI decoding format that it publishes. For the file format supported by other third-party decoders, or for copyright reasons, Windows 7 does not support it by default, so even if the user is installing. After the corresponding decoder, the system still does not support it.

But for AVI and WMV files, after installing the third party "Almighty Player", you can re-edit the file association back to the system default Windows Media Player 12.

Windows Media Player 12 uses Windows Media Player 12 to preview video files directly in the folder. I don't know if the content learned in the above course is helpful to you?
