How to set English (UK) as default editing language in Word 2007?

"Go to Start > All Programs > Microsoft Office > Microsoft Office Tools > Microsoft Office 2007 Language Settings.
When you have done that, you will see a window as shown below:

Ensure that the enabled editing languages you need are in the Enabled Editing Languages box on the right hand side and that the default the Primary Editing Language is set in the box at the bottom of the window as shown above. This will be the default dictionary.

Edit:

Try this:

Right click on a misspelled word in your document
Language –> Set Language –> select preferred language (e.g. English (UK)) –> Default… –> YES –> OK."

I don't see the language in the status bar. The language tool is also found under Review | Set Language. Choose the default language then the "Default..." button.
