PROBLEM: You view your source and see this line...
link rel="wlwmanifest" type="application/wlwmanifest+xml" href="http://www.example.com/wp-includes/wlwmanifest.xml"
SOLUTION: Add the following lines to the bottom of your functions.php file.
WHY: wlwmanifest.xml is the resource file needed to enable tagging support for Windows Live Writer. Some themes have this added especially the newer ones. Is it necessary? Probably not unless you have a client who is completely stupid when it comes to doing anything online. Will it hurt your bandwidth? No.
