How to modify the file association and open mode under Windows 7

Because the work needs to analyze the source of a message and other information, because I am used to using Office Outook to view the mail attribute information, and the current system default mail program is Windows. Live Mail, so use "Open with" to specify that the message is opened by Office Outlook, but it is conceivable that the opening method is inadvertently removed without removing the "Always use the selected program to open such a file".

And this operation did not make Office Outlook correctly open the mail file (.eml type), now you can only restore the previous state, according to the previous experience of using Windows XP in the "folder options" I can set the file key and open mode, but I am confused under Windows 7!

Click "Set Default Program", we can see the default program currently registered in the system in the program list box on the left side of the figure below, select Windows Live Mail, and click "Select this program's default" on the right. Value", then check the extension of type ".eml" in "Setup Program Association" and click OK to complete the setting.

Of course, we can also specify the opening method of a specific file type by clicking "Associate file type or protocol with program" in the default program setting panel.
