Windows 11's latest testing builds (versions 26120.5790 and 26220.5790) expand the Windows Studio Effects feature to support a wider range of webcams, including USB webcams and rear cameras on laptops with Copilot+ technology. Users can activate this feature by navigating to Settings > Bluetooth & devices > Cameras and enabling "Use Windows Studio Effects" in advanced settings.

The expansion of Windows Studio Effects is initially rolling out to Intel®-powered Copilot+ PCs, with support for AMD and Snapdragon devices expected soon. Additional updates include improvements to File Explorer and fixes for various issues, while known issues include potential bugchecks during hibernation and audio problems.
