Solution 1Recommended

Clear Office Credentials and Remove Registry Remnants

Remove leftover cached credentials and old registry entries that are triggering the false end-of-support warning.

Even after uninstalling Office 2013, Windows may retain old credentials or registry keys that cause the system to believe the outdated software is still active. Clearing these remnants usually resolves the persistent warning message.

1
Clear cached Windows credentials

Open the Control Panel, navigate to 'Credential Manager', and click on 'Windows Credentials'. Locate and remove any saved credentials associated with Microsoft Office or Office 2013.

2
Open the Registry Editor

Press the Windows key + R, type 'regedit' into the Run dialog, and press Enter to launch the Registry Editor.

3
Remove Office 2013 remnants

Carefully navigate to the Microsoft Office registry paths (such as HKEY_CURRENT_USER\Software\Microsoft\Office\15.0) and delete the keys related to the old Office 2013 installation. If you are uncertain about which keys to delete, contact Microsoft Support for guidance.

4
Restart your computer

Close the Registry Editor and restart your PC. Check Windows Settings to confirm the end-of-support warning has been removed.

Purchased Products List: The Office Professional 2013 record shown under purchased products is permanently associated with your Microsoft account history. It generally cannot be removed by making changes to your local computer.

Frequently Asked Questions

Why does Windows show an Office 2013 warning when I have Microsoft 365?

This usually happens because leftover registry keys or cached credentials from your previous Office 2013 installation are still present on your computer, causing Windows Settings to incorrectly detect the old version.

Can I delete old Office purchases from my Microsoft account?

No, previous software purchases like Office Professional 2013 are permanently linked to your Microsoft account's purchase history and cannot be removed by changing local system settings.

Is it safe to delete leftover Office registry keys?

While deleting leftover keys can fix warning issues, modifying the registry is risky. Always back up the registry before making any changes. If you delete the wrong keys, it could damage your operating system or your current Microsoft 365 installation.
