Question about Outlook Express

I backed up a Windows 7 system and restored it to factory state by doing a system recovery because the system was seriously infected with viruses.  I couldn't do the export before the system recovery.

Now having the Windows 7 system reset to its brand-new state I am trying to restore the Windows Mail account.  In fact, I can't tell if it was a Window Mail or Windows Live Mail before.  I don't know if the file locations for messages and contacts of these two mail are different.

When I go to to c:\users\%username%\AppData\Local\Microsoft\, I can't see Windows Live Mail but Windows Mail.  So does it mean it was a Windows Mail system not a Windows Live Mail system before.  I copied the backed-up files in the Windows Mail system over to the directory of the same path in the newly recovered system, however it does not seem to make any difference when I open Windows Live Mail which is the only mail program on the newly recovered Windows 7 system.

Can someone confirm me the locations of the files for messages and contacts for Windows Mail and Windows Live Mail in Windows 7 Home operating system.  Can I simply copy the files over?  With Outlook 2007 and 2010 it usually works if I simply copy the files over or import from the backed up file.  Also what file names should they be so that I can easily identify them?  Are the email accounts and password setup need to be re-entered like Outlook 2007/2010 or are stored in files which I can simply copy over to the new system?
