Fix Custom Ribbon Loading Slowly in Excel on Windows 11
Question details
The user is experiencing significant delays when loading or navigating a custom Excel ribbon on Windows 11, whereas older operating systems load it normally.
- Product
- Microsoft 365 Excel
- Device & OS
- Windows 11
- Scenario
- Opening and navigating an Excel workbook that contains a custom ribbon created via the third-party Office RibbonX Editor, especially when stored on a shared network drive.
- Observed behavior
- The custom ribbon takes a long time to load, and there is a noticeable lag when switching between the Home tab and the custom tab.
Ensure you have saved a backup copy of your workbook locally on your desktop, as testing files over a shared network drive can interfere with identifying the actual performance issue.
Install Office Updates and Run Excel in Safe Mode
Updating Office ensures you have the latest performance patches for Windows 11, while Safe Mode helps identify if background add-ins are conflicting with the custom ribbon.
Because the Custom UI Editor is a third-party tool, compatibility issues can arise with newer Windows 11 updates. Verifying your Microsoft 365 build and isolating add-ins is the most effective troubleshooting step.
Open Excel, navigate to 'File' > 'Account', click 'Update Options' under Product Information, and select 'Update Now' to ensure you are on the latest Microsoft 365 build.
Press the 'Windows + R' keys on your keyboard to open the Run dialog. Type 'excel /safe' and press Enter to launch Excel in Safe Mode.
Open the affected workbook with the custom ribbon. If the tabs switch smoothly without delay, a third-party add-in or extension is causing the slowdown.
To isolate the culprit, go to 'File' > 'Options' > 'Add-ins'. Select 'COM Add-ins' from the Manage drop-down and click 'Go'. Uncheck the items one by one, restarting Excel normally each time until the lag disappears.
Test a Local Copy of the Workbook
Network latency can severely impact the loading times of custom XML elements fetched from a shared network location.
Switch to WPS Office for a Faster, Lightweight Experience
If Microsoft Excel performance issues and add-in conflicts persist on Windows 11, consider switching to WPS Office. It provides a highly compatible, fast-loading spreadsheet tool that handles your daily data tasks smoothly without the lag of complex third-party custom ribbons.
- 1. Download the App: Visit the official WPS website and download the free WPS Office installer.
- 2. Install WPS Office: Run the installer and follow the on-screen instructions to set up the software on your Windows 11 PC.
- 3. Open Your Spreadsheets: Launch WPS Spreadsheets and open your existing .xlsx files to enjoy a fast, responsive editing experience.
Frequently Asked Questions
Why does my custom Excel ribbon load slower on Windows 11 than on older OS versions?
Windows 11 manages UI rendering and background processes differently. If you are using a third-party tool like the Office RibbonX Editor, its legacy XML configurations may not be fully optimized for the newer operating system or the latest Microsoft 365 builds.
Can network latency cause Excel interface lags?
Yes. If your workbook containing custom UI XML is stored on a shared network drive, Excel must continuously fetch these structural elements over the network. High latency can cause significant delays when switching tabs.
How do I know if an add-in is causing my Excel ribbon to run slowly?
You can launch Excel in Safe Mode by holding the 'Ctrl' key while clicking the application icon, or by typing 'excel /safe' in the Run dialog. If the custom ribbon loads quickly in Safe Mode, a background add-in is likely interfering with Excel's performance.
