Dear Joan,
Thanks for posting the thread on our forum.
Yes, it replaces Spell Check in the latest version of the Word 365 application. The Editor feature has more features than Spell Check. It is an AI-powered service that helps bring out your best writer in more than 20 languages, whether you are writing a Word doc, composing an email message, or posting on a website like LinkedIn or Facebook.
For your reference: Microsoft Editor checks grammar and more in documents, mail, and the web
The Spell Check UI
The Editor UI
So I suggest you use it if it is available in your Word application. Regarding "When typing a message in Word I virtually can not use Editor. It freezes up the program, shut down the program then restart without my direction. ", may I know whether you are using the latest version of the Office applications? If no, I suggest you check if you can update the version. If yes, update the version, restart the computer and do a test to see the result. Meanwhile, upload a full screenshot of the Account page in the Word application you are using for our reference. You can access the page via clicking on File>Account.
Note: Remove any private information before uploading the screenshots.
Moreover, I suggest you log into the computer with the administrator account>go to Control Panel>click on Programs>right-click on the Office applications' icon>Change>check whether there is an Online Repair option. If yes, run it, restart the computer and then do a test to see the result.
Best Regards,
Cliff
