Edit Windows Live Writer Custom Dictionary

Windows Live Writer is a great tool for writing and posting blog posts, but its spell check unfortunately doesn’t include many common technical words. This is how you can easily edit your custom dictionary and add your favorite words.

Customize the Live Writer Dictionary

Adding an individual word to the Windows Live Writer dictionary works as expected. Right-click on a word and select Add to Dictionary.

And it’s easy to change the default spell checker settings, too. On the menu, click Tools, then Options, and select the Spelling tab in this dialog box. Here you can choose the language of your dictionary and enable / disable real-time spell checking and other settings.

But there is no obvious way to edit your custom dictionary. Editing the custom dictionary directly is good if you accidentally add a misspelled word to your dictionary and want to remove it, or if you want to add many words to the dictionary at once.

Live Writer actually stores your custom dictionary entries in a plain text file located in your appdata folder. It is saved as User.dic in the folder C: Users user_name AppDataRoamingWindows Live WriterDictionaries. The easiest way to open the custom dictionary is to enter the following in the Run box or in the address bar of an Explorer window:

Appdata Windows Live Writer Dictionaries User.dic

This will open the User.dic file in your default text editor. Add any new words to the custom dictionary on separate lines, and remove any misspelled words that you have accidentally added to the dictionary.

Microsoft Office Word also stores your custom dictionary in a plain text file. If you already have many custom words and want to import them into Live Writer, enter the following in the Run command or in the Explorer address bar to open the Word custom dictionary. Then copy the words and paste them into Live Writer’s custom dictionary file.


Don’t forget to save your changes when you’re done. Note that changes to the dictionary may not appear in Live Writer’s spell checker until you restart the program. If it is currently running, save any messages you are working on, exit, then reopen, and all new words should be in the dictionary.


Whether you use Live Writer on a daily basis at work or occasionally post an update on a personal blog, adding your own custom words to the dictionary can save you a lot of editing time and frustration. Also, if you’ve accidentally added a misspelled word to the dictionary, this is a great way to undo your mistake and make sure your spelling is up to par.
