To enable dark mode in Google Chrome on Windows 10, you have two main options: activating the system-wide dark theme or enabling Chrome's experimental dark mode for web content.

Method 1: Enable Dark Mode via Windows 10 System Settings

1. Open Windows Settings by pressing Windows + I or right-click on the desktop and select Personalize.
2. Go to Personalization > Colors.
3. Under "Choose your color," select Dark.
4. This will switch Windows 10 to dark mode system-wide, and Chrome’s interface (menus, toolbar, settings, new tab page) will automatically adopt the dark theme

Note: This method changes Chrome’s UI to dark but does not make websites dark.

Method 2: Enable Dark Mode for All Websites in Chrome (Force Dark Mode)

To make websites also appear in dark mode, you need to enable Chrome’s experimental "Force Dark Mode for Web Contents" flag:

1. Open Chrome and enter the URL:
   chrome://flags/#enable-force-dark

2. Find "Force Dark Mode for Web Contents".

3. Change its setting from Default to Enabled.

4. Relaunch Chrome when prompted.

This forces all websites to display in dark mode by inverting colors and adjusting styles, even if the sites don’t natively support dark themes

Optional: Create a Chrome Shortcut to Always Launch in Dark Mode

You can also create a desktop shortcut that forces Chrome to start in dark mode:

1. Right-click on the Chrome shortcut and select Properties.

2. In the Target field, add a space after the path and append:
   -force-dark-mode

3. Click Apply and OK.

4. Launch Chrome using this shortcut to open it in dark mode

By combining the Windows dark theme with Chrome’s force dark mode flag, you get a comprehensive dark experience in Chrome on Windows 10.
