Microsoft blames Windows gaming issues on RGB lighting devices
Microsoft says some recent Windows updates may cause certain games to crash, freeze, or fail to open on computers that use accessories with customizable colored lights, such as keyboards, mice, or other connected devices. The issue appears tied to how these light-enabled accessories interact with the updated system.
Who is at risk
People who recently installed the August 2026 Windows updates and use gaming accessories or other plugged-in devices with color-changing lights are most at risk.
What to watch for
Watch for games that suddenly stop opening, crash shortly after starting, or become unstable after a recent Windows update.
What to do
If this started after updating Windows, disconnect or temporarily disable light-control software for color-changing accessories and check for new updates from Microsoft and the device maker.
