How to Enable Light Theme in Windows 10

This guide shows you how to switch your Windows 10 PC from the default dark or custom theme to the built-in light theme, which brightens the taskbar, Start menu, and many apps. You’ll also learn how to adjust the accent color and make apps use light mode, plus what to do if the setting doesn’t stick.

What You’ll Need

A PC running Windows 10 (any recent version, ideally 1903 or later)
Administrator access (not strictly required, but helpful if Settings won’t open)
About 2 minutes of your time

Step-by-Step

Open Settings. Click the Start button (Windows logo) in the bottom-left corner, then click the gear icon labeled Settings. Alternatively, press Windows + I on your keyboard.
Go to Personalization. In the Settings window, click the Personalization tile (it has a paintbrush icon).
Select Colors. In the left sidebar, click Colors.
Choose your color. Scroll down to the section labeled Choose your color. Click the drop-down menu and select Light.
Check the effect. The taskbar, Start menu, Action Center, and many built-in apps (like Settings, Store, and Mail) should immediately turn light. If they don’t, proceed to the next step.
Enable light mode for apps (optional). If some apps still appear dark, scroll further down to Choose your default app mode and select Light. This forces apps that support the setting to use light mode.
Adjust accent color (optional). While still in the Colors page, you can pick an accent color for Start, taskbar, and title bars. Scroll to Accent color and choose a swatch, or click Custom color for a specific shade. If you want the accent to appear on the Start menu and taskbar, make sure Show accent color on the following surfaces has the appropriate checkboxes ticked.
Close Settings. Your changes are saved automatically. You can close the window and enjoy the light theme.

Common Mistakes

Choosing “Custom” instead of “Light.” The “Custom” option lets you set separate modes for Windows and apps. If you pick Custom, you must set both drop-downs to Light to get the full light theme.
Forgetting to scroll down. The “Choose your color” drop-down is near the top, but the “default app mode” setting is further down. Many users miss it and wonder why apps stay dark.
Not checking app-specific settings. Some third-party apps (like web browsers) have their own theme settings that override Windows. You may need to change those individually.
Expecting all apps to change. Older or poorly coded apps may not respond to the Windows theme setting. This is a limitation of the app, not your configuration.

Tips

Use the shortcut. Press Windows + I to open Settings directly from anywhere.
Toggle quickly. If you frequently switch between light and dark, consider using the Action Center (click the speech bubble icon in the taskbar) and look for a Dark mode or Light mode button if you have a recent Windows 10 update. Not all versions have this, but it’s handy when available.
Set a custom accent color. If the default colors don’t appeal to you, click Custom color and use the color picker to match your wallpaper or style.
Make title bars light too. In the same Colors page, scroll to Show accent color on the following surfaces and tick Title bars if you want a colored (or light) title bar instead of the default white.
Check for updates. Some theme features were added in later Windows 10 updates. If you don’t see the options described, run Windows Update to ensure you have the latest version.

Troubleshooting

The light theme doesn’t apply. First, make sure you selected Light in the “Choose your color” drop-down, not just in the app mode. If it still doesn’t change, try restarting your PC. Sometimes the theme needs a reboot to fully apply. If that fails, check for Windows updates—older builds have bugs that were later fixed.

Some apps remain dark. As mentioned, some apps have their own theme. For example, Microsoft Edge has a separate theme setting in its own settings menu. Open the app’s settings and look for a “Theme” or “Appearance” option. If the app is a classic desktop program (like Notepad), it may not support theming at all.

The Start menu and taskbar are still dark. This can happen if you have a high-contrast mode enabled. Go to Settings > Ease of Access > High contrast and make sure it’s turned off. Also, check if you have a third-party theme or customization tool installed that overrides Windows settings.

Settings won’t open. If clicking Settings does nothing, try pressing Windows + I. If that also fails, restart your PC. If the problem persists, run the System File Checker by opening Command Prompt as administrator and typing sfc /scannow. This will repair corrupted system files that may be causing the issue.

Frequently Asked Questions

Q: Will the light theme affect battery life?
A: On devices with OLED screens, dark themes can save battery because black pixels are turned off. Light themes generally use slightly more battery on OLED, but on LCD screens the difference is negligible.

Q: Can I schedule light and dark modes to switch automatically?
A: Windows 10 does not have a built-in scheduler for themes. You can use third-party tools like Auto Dark Mode, but that’s not part of the OS.

Q: Why is my taskbar still dark even after selecting Light?
A: This often happens if you have “Show accent color on the following surfaces” set to taskbar and Start, and your accent color is dark. Set the accent color to a light shade or uncheck the taskbar option.

Q: Does the light theme change the color of file explorer?
A: Yes, File Explorer uses the default app mode. If you set it to Light, the title bar and ribbon will be light, but the background of the file list remains white regardless.

Q: Can I use a light theme but keep dark apps?
A: Yes. Choose “Custom” in the “Choose your color” drop-down, then set “Choose your default Windows mode” to Light and “Choose your default app mode” to Dark.

Q: Will the light theme affect how my desktop icons look?
A: No, the theme does not change your wallpaper or icon colors. It only affects the system UI elements like the taskbar, Start menu, and built-in apps.
