Before modifying the Windows Registry, ensure you have created a backup of your registry or a system restore point, as incorrect edits can cause severe system damage.
Reset Office Settings Using Registry Editor
Clear the cached configuration for Microsoft Excel to resolve localized graphical and formatting glitches.
This issue is often tied to corrupted application preferences. Resetting the Excel registry key will force the application to regenerate its default settings. Microsoft warns that incorrectly editing the registry can cause serious problems, so proceed with extreme caution.
Save your work and ensure all Microsoft Excel and PowerPoint windows are completely closed.
Press the Windows key + R to open the Run dialog, type 'regedit', and click OK to open the Registry Editor.
Navigate through the folders to find the Microsoft Office Excel registry folder. The path typically looks like: HKEY_CURRENT_USER\Software\Microsoft\Office\[Version]\Excel\Options.
Right-click the Excel folder or the Options subkey, select Rename (e.g., change it to Excel.old), or select Delete to remove it. Confirm your action.
Close the Registry Editor, restart your computer, and open your Excel or PowerPoint file to verify that the shapes and pie charts are rendering correctly.

View and Edit Your Charts Perfectly with WPS Office
If your shapes and pie charts are still distorted in Microsoft Office or you want to avoid risky system registry edits, try WPS Office. It is a free, lightweight suite that is fully compatible with Microsoft Office formats, ensuring your charts display correctly and natively without requiring complex troubleshooting.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installation package for your device.

- 3. View Charts Flawlessly: Edit and present your documents immediately, with all round shapes and pie charts retaining their correct proportions.

Frequently Asked Questions
Why do my Excel pie charts appear oval instead of round?
This graphical distortion is usually caused by corrupted cached settings within your Microsoft Office application or an incompatibility with your display scaling. Resetting the Excel settings often forces the application to render the geometry correctly again.
Can a corrupted Excel file cause shapes to change dynamically?
Yes, file corruption can occasionally lead to formatting errors. However, if the same file opens perfectly on another computer or in alternative software like WPS Office, the issue is almost certainly with your local Office installation rather than the file itself.
How do I safely back up the registry before fixing this issue?
Open the Registry Editor, click on 'File' in the top menu, and select 'Export'. Choose a secure location on your drive to save the backup file, and ensure you select 'All' under the Export range before making any modifications.
