Enabling Dark Mode in Windows 10 and 11

Introduction / Why This Is Useful

Dark Mode in Windows is not just a trendy fashion, but a practical feature that:

• Reduces eye strain, especially in low-light conditions or during prolonged computer work.
• Saves battery charge on devices with OLED screens, where black pixels are effectively turned off.
• Creates a contrasting and modern look for the working environment.

In this guide, you will learn how to enable and configure the dark theme in Windows 10 and 11, both system-wide and for individual components.

Requirements / Preparation

To follow this guide, you need:

• Operating system Windows 10 (version 1903 'May 2019 Update' or newer) or Windows 11.
• A user account with standard user rights (administrator privileges are not required to change personalization settings).

Step-by-Step Instructions

Step 1: Open Personalization Settings

Press the Win + I key combination to launch the Windows Settings app. In the left navigation pane, select the Personalization section, and then from the list of settings, choose the Colors tab.

Step 2: Select Default Dark Mode

In the panel that opens, find the "Choose your default mode" section. Here there are two dropdown lists:

• "Choose your default Windows mode" — controls the main color scheme of the Windows interface (system windows, menus, taskbar).
• "Choose your default app mode" — controls the theme for built-in Microsoft apps (e.g., Settings, Weather, Calculator).

Set both lists to "Dark". This ensures a uniform dark appearance for the entire system and its built-in applications.

💡 Tip: If you want the system to be dark while built-in apps are light (or vice versa), set different values for these two lists.

Step 3: Configure Accent Color (Optional)

Further down in the same "Colors" section is the "Choose your accent color" option. In a dark theme, this color will be used for:

• Buttons on the taskbar and Start menu.
• Selected items in File Explorer and Settings.
• Scrollbars.

You can select one of the suggested colors or click "Show accent color on title bars and window borders" to open the palette and set your own RGB or HEX color. It is recommended to choose bright, but not overly garish shades (e.g., blue, teal, purple) that are readable against a dark background.

Step 4: Apply Dark Theme to Specific Elements (Granular Control)

Further down, in the section "Show accent color on the following surfaces", you can precisely control where exactly the dark theme or your chosen accent color will be applied.

For each element (e.g., "Title bars and window borders", "Start, taskbar, and action center", "Title bars and window borders"), three options are available:

1. "Dark" — the element will be displayed in a dark color (usually dark gray or black).
2. "Light" — the element will remain light.
3. "Custom" (or using your accent color) — the element will be colored with the accent color chosen in Step 3.

By default, after enabling the global dark mode, most elements are already set to "Dark". You can experiment, for example, by leaving the taskbar dark while setting window title bars to light for better readability.

Step 5: Verify the Result

After making changes, close the Windows Settings app. The interface should update automatically. Check:

• The Start menu and taskbar.
• The File Explorer window (including the sidebar and address bar).
• The Settings app (if you changed the setting for apps).
• Built-in utilities like Calculator or Weather.

If configured correctly, the primary background of these elements will be dark (deep gray or black), while text and icons will be light.

Additional Methods (For Advanced Users)

Besides the graphical interface, Dark Mode can also be managed via the Registry Editor or PowerShell. These methods are useful for automated deployment in corporate environments or if the graphical interface is unavailable.

Via PowerShell (requires running as Administrator):

# Enable dark mode for system (AppsUseLightTheme = 0)
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" -Name "AppsUseLightTheme" -Value 0

# Enable dark mode for apps (SystemUsesLightTheme = 0)
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" -Name "SystemUsesLightTheme" -Value 0

# Changes may require restarting File Explorer or signing out/in.

⚠️ Important: Incorrect registry edits can damage your system. Create a restore point before editing.

Verifying the Result

Besides visual inspection, the current status of the dark theme can be checked via PowerShell:

Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" | Select-Object AppsUseLightTheme, SystemUsesLightTheme

• Value 0 — Dark mode is enabled.
• Value 1 — Light mode is enabled.

Potential Issues

• Dark theme does not apply to third-party applications. Most modern programs (Chrome, Firefox, Discord, VSCode) have their own theme settings. You need to go into their preferences and enable dark mode separately. Ensure the program has the "System theme" or "Dark" option selected.
• Changes in "Colors" have no effect. Try restarting your computer. If the problem persists, check for Windows updates (Settings → Update & Security → Windows Update). Sometimes issues are fixed in cumulative updates.
• Artifacts or unreadable text appear in individual windows. This can be related to outdated software or conflicts with third-party interface customization programs (e.g., theming tools). Try temporarily disabling such programs or revert to the default theme via Control Panel → Appearance and Personalization.
• PowerShell method does not work (access denied). Ensure you launched the console as Administrator (right-click the PowerShell icon → "Run as administrator").
