Google has released Chrome 74 into the beta channel and with it comes the browser's highly anticipated Dark Mode feature for Windows 10. In Chrome 74, Google has finally made it possible for Chrome to detect when dark mode is enabled in Windows 10 and switch to dark mode in the browser.

While Mac users received a working Dark Mode in Chrome 73, the code for synchronizing Windows 10's color settings with Google Chrome's Dark Mode had not been wired up in time. This feature is now available in Chrome 74 beta that was released today.
