Solution 1Recommended

Run Excel in Safe Mode and Disable Add-ins

Starting Excel in Safe Mode bypasses third-party add-ins, helping identify if a faulty extension is causing the color-fill freeze.

Many Excel performance issues, including freezing during formatting, are caused by incompatible COM add-ins or leftover extensions from older Office installations.

1
Launch Safe Mode

Press Windows + R to open the Run dialog box. Type 'excel /safe' and press Enter to launch Excel in Safe Mode.

2
Test Cell Formatting

Open a new or existing spreadsheet and try changing a cell color. If the issue is gone, the problem is likely an add-in.

3
Access Add-in Settings

Click on File > Options > Add-ins.

4
Disable COM Add-ins

Select 'COM Add-ins' from the Manage drop-down menu at the bottom and click 'Go'. Uncheck all add-ins and click OK. Restart Excel normally to see if the freeze is resolved.

Run Excel in Safe Mode and Disable Add-ins
Success Tip: If disabling all add-ins works, re-enable them one by one to pinpoint exactly which add-in is causing the crash.

Frequently Asked Questions

Why does Excel only freeze when applying formatting or cell colors?

Formatting features like applying cell colors rely on graphics hardware acceleration and specific display drivers. If these drivers are outdated or conflicting with a background process, Excel may hang while trying to render the visual change.

Does hardware acceleration affect Excel performance?

Yes, hardware graphics acceleration can sometimes cause display issues or freezing in Office apps. You can try disabling it in Excel by going to File > Options > Advanced > Display, and checking 'Disable hardware graphics acceleration'.

Will an online repair delete my Excel files?

No, performing a Microsoft Office Online Repair only fixes the application's underlying installation files. Your personal spreadsheets, macros, and data will remain untouched on your hard drive.
