I used to write posts using Microsoft Word. After updating to WordPress 4.1 blogging was not possible anymore . In WordPress the settings for XML-RPC disappeared.
Microsoft is offering a free bundle of software called : Windows Essentials
Install only Windows Live Writer from this bundle. It is better than Word for blogging as you can apply categories etc.
Info: to change the path where Live Writer saves your local documents add the following RegKey
Windows Registry Editor Version 5.00
