- Observed behavior
- After installing the new Office 2024 product, the account page still displays the older Office 2021 edition, and the purchased product appears to be a volume-licensed version mislabeled for retail.

Completely Uninstall Previous Office Versions
Use your system settings or Microsoft's specialized troubleshooting tool to remove all remnants of the old Office installation.
To ensure a clean installation of a newer Office version, all files, registry keys, and configurations from the previous installation must be completely removed.
Navigate to your system's Settings menu and open the 'Apps' or 'Installed apps' section.
Locate 'Microsoft Office Home and Student 2021' in the application list, select it, and click 'Uninstall'. Follow the on-screen prompts to remove the program.
If standard uninstallation fails, download and run the Microsoft Office Uninstall Troubleshooter from the official Microsoft support website to automatically clear leftover files.
Once the uninstallation process is fully completed, reboot your computer to apply the changes.
Verify Your Office 2024 License Authenticity
Check if your newly purchased Office 2024 license is a genuine retail product or a fraudulent volume license.

Frequently Asked Questions
Why does my account still show Office 2021 after installing Office 2024?
This usually happens if the previous version was not completely uninstalled from the system registry, or if the new Office 2024 product key is invalid. When an invalid key is rejected, Microsoft's servers may fall back to displaying your last legally registered license.
Can I buy Office LTSC Professional Plus 2024 for personal home use?
No. Office LTSC Professional Plus 2024 is a volume-licensed product intended solely for businesses and organizations. It is not manufactured or authorized for standard retail sale to individual consumers.
What should I do if I bought a fake Office license key online?
Immediately contact the marketplace platform's customer service (such as Amazon or eBay) to report the fraudulent seller and request a refund. Do not attempt to use unauthorized volume keys, as Microsoft frequently audits and blocks them.
How do I completely remove all traces of an old Office installation?
The most effective method is to download and run the official Microsoft Office Uninstall Troubleshooter tool. This utility is designed to detect and remove leftover registry entries, scheduled tasks, and files that standard Windows uninstallation methods might miss.
