Windows Live Mail and Windows Live Essentials are retired products and no longer supported. Updates for Windows Live Mail 2012 are no longer offered, and Windows Mail itself has been removed from newer versions of Windows. This can cause Windows Live Mail to stop working reliably from one day to the next.
The recommended mitigation is to reinstall Windows Essentials (which includes Windows Live Mail) or move to another mail program that can read .eml and .nws files.
If Windows Mail has been removed on the system, entry points and associations for mail will no longer work, and a different email application must be installed and set as the default mail handler.
