How to Remove a Wikipedia Add-In That Keeps Opening in Excel
Question details
The user needs to completely remove a Wikipedia add-in that continues to launch automatically in Excel even after attempting to uninstall and reinstall it.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Attempting to permanently delete a persistent third-party Wikipedia add-in from the Excel interface.
- Observed behavior
- The Wikipedia add-in keeps reappearing and opening automatically in Excel because its residual registry entries were not properly deleted during standard uninstallation.
Ensure Microsoft Excel is completely closed before proceeding. Since this fix requires modifying the Windows Registry, it is highly recommended to create a registry backup or a system restore point first.
Delete the Add-In Folder Using the Registry Editor
Manually remove the leftover registry keys that force the Wikipedia add-in to keep opening in Excel.
When standard removal methods fail, residual keys in the Windows Registry often cause add-ins to persist. Deleting the specific folder for the add-in will resolve the issue.
Make sure Excel is closed. Press the Windows Key + R on your keyboard to launch the Run command window.
Type 'regedit' into the text box and press Enter. Click 'Yes' if prompted by User Account Control for administrative permissions.
In the Registry Editor, carefully navigate through the left pane to the following path: HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\Addins.
Expand the Addins folder, locate the subfolder associated with the Wikipedia add-in, right-click on it, and select 'Delete' to permanently remove the configuration.

Remove the Add-In via the Office Interface
Verify that the add-in has been properly uninstalled through Excel's standard Add-ins menu before resorting to registry edits.
Perform a Clean Reinstallation of Office
If repeated removal attempts and registry edits fail, uninstalling and reinstalling Microsoft Office will reset all configurations and clear corrupted add-in caches.

Frequently Asked Questions
Why does the Wikipedia add-in keep opening in Excel after I removed it?
Even after you remove an add-in from the Excel interface, its configuration files or registry keys can occasionally be left behind on your Windows system. These residual entries force Excel to continuously reload the add-in upon startup.
How do I safely back up the Windows Registry before deleting an add-in folder?
To back up the registry, open the Registry Editor, click 'File' in the top menu bar, and select 'Export'. Choose 'All' under the Export Range section, name your backup file appropriately, and save it to a secure location on your hard drive.
Will deleting the registry folder affect my other Excel add-ins?
No. As long as you only delete the specific subfolder that corresponds to the Wikipedia add-in under the 'Addins' directory, your other installed add-ins and core Excel functions will remain completely unaffected.
Can I disable the Wikipedia add-in without completely uninstalling it?
Yes, you can temporarily disable it by navigating to File > Options > Add-ins in Excel. Select 'COM Add-ins' or 'Excel Add-ins' from the Manage drop-down menu, click 'Go', and uncheck the box next to the Wikipedia add-in.
