Hello @CJ
Welcome to the Microsoft Q&A Community!
Thank you for contacting us regarding the ability to close multiple Excel windows simultaneously. In previous versions of Excel, this could be achieved by right-clicking the Excel icon on the Windows taskbar and selecting the option to close all windows.
As I tested on my side with the latest Excel build (Version 2511), this functionality is available again. If you do not see this option, please follow the steps below:
- Ensure that both Excel and Windows are fully updated. Updates often restore or improve features, including this one.
- If updating does not resolve the issue, you can repair Excel by navigating to: Control Panel > Programs > Microsoft Office > Change > Quick Repair. For Windows 10 and 11, try following the steps in this article Repair an Office application - Microsoft Support
To assist you further, I kindly request that you provide a screenshot showing what appears when you right-click the Excel icon on your Windows taskbar. This will help me confirm whether the option to close all windows is visible in your version.
Your feedback is very important to us. Please share your suggestion through the Excel Feedback Portal or directly on Excel by going to File, then Feedback, then Make a Suggestion. This ensures that our development team is aware of your request and can consider it for future improvements.
Please let me know if you require detailed instructions for any of these steps. I look forward to your response.
