Symptoms
You might be experiencing this problem if you notice:

- •Explorer title bar is dark but file list area is white
- •Dark mode flickers or reverts in Explorer

Common Causes
- ⚠Windows theme cache corrupted

Solutions
Solution 1: Reset Dark Mode Settings
- 1Settings → Personalization → Colors
- 2Under "Choose your mode": switch to "Light"
- 3Wait 10 seconds → switch back to "Dark"
- 4If using "Custom": set both "Windows mode" and "App mode" to Dark
- 5Also: turn OFF then ON "Transparency effects"
- 6Close and reopen File Explorer to check
- 7If still broken: sign out and sign back in
Solution 2: Clear Theme Cache
- 1Close all Explorer windows
- 2Open CMD as Admin:
- 3taskkill /f /im explorer.exe
- 4Delete theme cache: del /f /q "%LocalAppData%\Microsoft\Windows\Explorer\ThemeCache*"
- 5Also clear icon cache: del /f /q "%LocalAppData%\Microsoft\Windows\Explorer\iconcache*"
- 6start explorer.exe
- 7Dark mode should now apply correctly
- 8If not: restart PC for full cache rebuild
Solution 3: Fix System Theme Components
- 1Remove any third-party theme tools (UltraUXThemePatcher, etc.)
- 2These modify system files and can break native dark mode
- 3Check for High Contrast: Settings → Accessibility → Contrast themes
- 4Ensure set to "None" (not a high contrast theme)
- 5Repair system files: CMD as Admin:
- 6sfc /scannow
- 7DISM /Online /Cleanup-Image /RestoreHealth
- 8Create a new user account to test — if dark mode works there, profile is corrupt
