Microsoft's preview update for Windows 11, KB5079391, initially supported display refresh rates exceeding 1,000Hz, potentially reaching up to 5,000Hz. The update was applicable to Windows 11 versions 25H2, 24H2, and 26H1. It introduced enhancements such as improved auto-rotation and HDR reliability, better power efficiency for USB4-connected monitors, detailed image descriptions for Copilot and Copilot+ PCs using Narrator, and redesigned dialog boxes in the Accounts settings menu. However, Microsoft retracted the update on March 27 due to installation issues, with plans to roll out the enhancements in a future release.
