About the file association and opening method in Win 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 the way" to specify the opening of the mail by Office Outlook, but the opening method is specified because of negligence, did not remove "always use the selected program to open this file", the results of the check can be imagined.


and after the implementation of this operation did not make the correct open Office Outlook mail file change (.eml type), and now must first restore the previous state, based on past experience using Windows XP in & ldquo; File key and open mode can be set in the folder option, but gOxiA is lost under Windows 7! I haven't found it for a long time, because it is the reason of the RC version. It is difficult to search for relevant information in the help system. At least through several keywords, I can't search for related help windows7 system download. But I am sure that the system will have a place to set up, which reminds me of the control panel
