Windows 7 and Word 2010 – Add .rtf (Rich Text Document) to ‘new’ context menu

The usual method to add another file type to the ‘new’ menu in Windows 7 does not work for Rich Text Documents, this is because Rich Text Documents (.rtf) are not “null” files.

To add ‘Rich Text Format’ to the ‘new’ context menu, you will need to create a document template, save it to %SystemRoot%\ShellNew and then add a registry key to the computer.

Note:
After added key to registry, need to wait for about 10 mins or more to see the option for new rtf file type to be added in the context menu
