One-time setting file under Vista and Windows7

Especially love to play software, I downloaded n browsers, I also tried a lot of players, every time I changed the software, I found out, oh, the file association is disordered. Now even the input method is secretly setting the default for you, and there is a domestic download software that is associated with all the files in the user's computer. …… Well, talk about how to change it back today.

In the newly installed system, Windows 7 programs that open AVI and MP3 audio files by default are Windows Media Player 12 (WMP12), but later installed XX video and XX playback, the default program changes. How to change it back? Find these files, right click, open the way to select WMP, and then set a default open program? In fact, don't, look at the following method, very simple, take WMP 12 as an example:

Click the Windows7“Start” button, and select "Default Program" in the pop-up menu.

Select “Windows Media Player” in the list on the left, and then click on the bottom right corner to select the default value for this program.

At this point, the system will go to the setup program association window, wow, a lot of things:

Ok, so you can batch Set it up.

This method is the same in both Windows 7 and Vista. Microsoft has left a "back door" for its own software.
