According to software developer Albacore, Windows 11 insider build 25295 comes with hidden settings that allows users to control device lighting. From the screenshots shared on Twitter, these settings for connected device lighting are located under the personalisation menu. Connected applicable devices connected to the Windows 11 PC will be listed, though not necessarily with their exact model names. Because of this, identifying which is which could be an issue sometimes. Though once a device is selected, you’ll be able to adjust the brightness, effect, speed and colour of the lighting. There’s even an option to make it match your Windows accent colour. For the available effects, the options include setting it to a Solid Colour, have it Blink, or having it cycle through the Rainbow colours. That last one is available in two different directions. All in all, pretty standard for RGB components and peripherals, with some more complex options specifically for keyboards not listed.
— Albacore (@thebookisclosed) February 10, 2023 Worth noting is that Albacore says that “The spec for this is from 2018 and references to the feature have been around for years”. Hints of it appearing again in a Windows 11 insider build, even if hidden, indicated that Microsoft may have picked this project up again after abandoning it before. With that in mind, it’s entirely likely that the company will drop it again before it gets to the point of general availability for everyone. (Source: Albacore / Twitter)
