This is a long-awaited blog - one I should have written ages ago...
In Microsoft Word, as part of Microsoft Office, when you are writing something in say, French, you usually get red lines under most of what you've written. This is because the dictionary is set to English. If you change it to French, it will hide these "errors", and then when you spell something in French wrong, it will give you French corrections!
To set this feature up, highlight the text on your document that you want to write in French. If you want to do the whole page, press and hold CTRL+A on your keyboard then release. Then, when you've selected it, go up to Tools > Language > Set Language. Scroll down to French (France) and then hit OK. And there you go! Instant French.
