Solution 1Recommended

Update Excel and Submit Feature Feedback

Since Microsoft does not currently provide a native settings toggle for this specific popup, ensuring you have the latest software build and submitting direct feedback is the officially supported approach.

Microsoft often rolls back or modifies intrusive features based on user feedback. Reporting the lack of a disable option directly to the development team helps prioritize a fix for future updates.

1
Check for Office updates

Open Microsoft Excel, click on 'File' in the top left corner, and select 'Account' from the bottom left menu. Click on 'Update Options' and choose 'Update Now' to install any pending patches.

2
Access the Feedback tool

Once updated, go back to the 'File' menu and select 'Feedback' (or 'Help' > 'Feedback').

3
Submit a feature request

Click on 'I Don't Like Something' and explain that the Optimize Performance popup appears too frequently on simple files and needs a dedicated 'Disable' switch in the Options menu.

Update Excel and Submit Feature Feedback
No Built-in Toggle: Currently, avoiding a registry edit means you cannot force-disable this feature. Keeping the app updated is the safest way to receive a fix once Microsoft addresses the community complaints.

Frequently Asked Questions

Why does Excel keep showing the Optimize Performance popup?

Excel automatically detects excess formatting, empty cells containing hidden data, or complex calculation chains that it believes might be slowing down the workbook. It triggers this popup proactively, even if you haven't noticed any actual performance issues.

Can I disable this Excel popup without editing the registry?

Currently, Microsoft does not provide a straightforward built-in toggle in the standard settings menu to disable this specific notification. Unless you are comfortable modifying registry keys, the best workaround is to ensure your software is updated and submit feedback to Microsoft.

Will clicking 'Optimize' alter my spreadsheet data?

Clicking 'Optimize' typically prompts Excel to remove unused formatting (like colors or borders in empty rows) to reduce file size. It is not designed to alter your actual data or formulas, but it's always recommended to keep a backup of your file before running optimization tools.
