Question details

The user needs to recover the blue or gray background color that usually appears when highlighting or selecting text.

Product: Microsoft Word
Device & OS: not provided
Scenario: Selecting or highlighting text within a document.
Observed behavior: Microsoft Word fails to display the standard blue or gray background over selected text, making it difficult to see what is currently highlighted.

Before you start

Before proceeding with add-in or registry modifications, open a brand-new blank document to see if the missing highlight issue is isolated to a single file, and verify that your system's Windows High Contrast settings are currently turned off.

Solution 1Recommended

Check Word and Windows Display Options

Reset specific display and ease of access settings that might be overriding the default text selection highlighting colors.

Open Windows Accessibility Settings

Press the Windows key + I to open Settings, then navigate to 'Ease of Access' (or 'Accessibility' in Windows 11).

Verify High Contrast Mode

Select 'High contrast' (or 'Contrast themes') from the sidebar. Ensure this feature is turned off, as high contrast themes automatically alter text selection colors across Microsoft Office.

Check Word Advanced Options

Open Microsoft Word, go to 'File' > 'Options' > 'Advanced'. Scroll down to the 'Show document content' section and ensure no custom background themes are interfering with normal display.

Solution 2

Disable COM Add-ins

Identify if a third-party add-in is conflicting with Word's display renderer and blocking the text selection background.

Solution 3

Reset the Office Registry Configuration

Rename the Word registry key so the application is forced to recreate a clean, default user configuration upon its next launch.

Frequently Asked Questions

Why did my text selection highlight suddenly disappear in Word?

This display issue is typically caused by a glitch in Windows High Contrast settings, a conflicting third-party COM add-in, or a corrupted Word user configuration registry key.

Can a Windows system update affect Microsoft Word text selection colors?

Yes, Windows system updates that alter display themes or accessibility features (such as contrast themes) can sometimes override or conflict with Word's default text highlighting settings.

Is it safe to rename the Office registry key to fix display issues?

Renaming the Word registry key is generally safe, as it forces the application to automatically create a fresh default configuration upon restart. However, it is highly recommended to export a backup of the key before making any changes.
