Repair the Microsoft Office Installation
Office files or registry settings can become corrupted during an update. Running the built-in repair tool can quickly restore default behaviors and fix color rendering issues.
Microsoft provides a built-in repair utility that scans for and fixes corrupted installation files. It is the most effective first step for post-update issues.
Open the Windows Control Panel and navigate to 'Programs and Features' (or 'Apps & features' in Windows Settings).
Locate Microsoft Office or Microsoft 365 in the list of installed applications, select it, and click 'Change' or 'Modify' at the top of the window.
Choose the 'Quick Repair' option and click 'Repair'. Follow the on-screen prompts. If the issue persists afterward, repeat the process and select 'Online Repair' for a more comprehensive fix.
Update Graphics Drivers and Adjust Color Profiles
Windows updates sometimes overwrite graphics drivers or color profiles, causing applications with hardware acceleration like Excel to render colors improperly.

Frequently Asked Questions
Why did my Excel cell fill colors change to grey or black after an update?
This often happens when Windows goes into a High Contrast mode after an update, overriding application colors. Check your Windows Accessibility settings by searching for 'High contrast settings' in the Start menu to ensure it is disabled.
Can a specific Excel add-in cause color rendering problems?
Yes, outdated or incompatible add-ins can interfere with Excel's display engine after an Office update. Try opening Excel in Safe Mode by holding CTRL while launching the app. If the colors render correctly, disable your add-ins one by one via File > Options > Add-ins to find the culprit.
Does the color profile of my monitor affect Excel alone?
Usually, an incorrect monitor color profile affects the entire Windows display. However, Excel uses hardware graphics acceleration which might react uniquely to driver changes. Disabling 'Hardware graphics acceleration' in Excel's Advanced settings (File > Options > Advanced > Display) can sometimes resolve app-specific color rendering issues.
How do I prevent Office updates from changing my workbook themes?
To prevent automatic updates from temporarily altering your workflow, you can disable Office updates by opening Excel, going to File > Account > Update Options, and selecting 'Disable Updates.' This should only be used as a temporary workaround until Microsoft patches the display bug.
