Frequently Asked Questions

Why did Microsoft 365 install itself on my computer when I already own Office 2019?

Sometimes major Windows feature updates or accidental clicks on Microsoft promotional banners can trigger a trial or background installation of Microsoft 365. This causes overlapping registries and conflicts with your standalone Office 2019 license.

Will repairing Office 2019 delete my documents or custom settings?

No, running a Quick Repair or Online Repair from the Control Panel only targets corrupted application files and resets registry keys. Your personal documents, templates, and customized settings will remain unaffected.

How do I get my spelling suggestions back in Word 2019?

The disappearing spell check is usually a symptom of a software conflict. Uninstalling any overlapping Microsoft 365 apps via Programs and Features, then repairing Office 2019, will typically restore the missing spelling suggestions.

Where can I get advanced help if my Office 2019 bugs persist?

If standard troubleshooting fails, you can seek specialized assistance by posting your detailed issue in the Microsoft Office Management forum, ensuring you specify that you are using Office 2019 rather than Microsoft 365.
