Windows 11 users eager for the smoothest possible gaming experience may soon have reason to celebrate. A recently released, and then quickly pulled, preview update – KB5079391 – introduces support for display refresh rates exceeding 1,000Hz, pushing the boundaries of what’s currently possible in PC gaming. While the update experienced installation issues and was temporarily removed by Microsoft, the underlying capability signals a significant shift in how Windows handles high-performance displays and prepares the operating system for future hardware advancements. This update to Windows 11 refresh rates is a key step for those seeking the most responsive and visually fluid gaming experience.
The update, initially rolled out on March 26, extends support up to an impressive 5,000Hz, according to internal documentation. This leap beyond the previous 1,000Hz limit is driven by emerging display technology, with manufacturers like Acer, AOC, and Philips showcasing 1,000Hz gaming monitors at CES 2026. Blur Busters, a website dedicated to display technology, played a crucial role in advocating for this increased support, with founder Mark Rehjon working directly with Microsoft to raise the maximum refresh rate. The company has not yet announced a firm date for the re-release of the update.
Beyond Refresh Rate: What Else Changed in KB5079391
The enhancements in KB5079391 weren’t limited to just refresh rates. Microsoft also focused on improving overall display performance, and accessibility. The update included improvements to auto-rotation functionality, enhancing its reliability, and bolstering HDR performance. Power efficiency for monitors connected via USB4 was also addressed, potentially leading to lower energy consumption. These changes demonstrate a broader commitment to optimizing the Windows 11 experience for a wider range of display setups.
Accessibility also received a boost with the introduction of detailed image descriptions for Copilot and Copilot+ PCs when using the Narrator screen reader. This feature aims to make digital content more accessible to visually impaired users. Microsoft refined the design of dialog boxes within the Accounts settings menu, offering a subtle but welcome user interface improvement.
Why the Push to 5,000Hz? Looking Ahead to Future Displays
The decision to support refresh rates up to 5,000Hz may seem ambitious given the current state of display technology, but it’s a strategic move by Microsoft to future-proof Windows 11. While 1,000Hz monitors are now available, albeit at lower resolutions (typically 720p), manufacturers are already planning for even faster displays. Blur Busters reports that 2,000Hz panels are anticipated by 2030, suggesting Microsoft is proactively accommodating these advancements. The 5,000Hz limit provides headroom for innovation and ensures Windows 11 remains compatible with the next generation of gaming monitors.
Previously, Windows operating systems capped refresh rates at 1,000Hz, creating a bottleneck for users investing in high-end display hardware. Increasing this limit required a fundamental update to the operating system’s display pipeline, a task Microsoft has now undertaken. The benefits of higher refresh rates are particularly noticeable in fast-paced gaming scenarios, where reduced motion blur and increased responsiveness can provide a competitive edge.
Installation Issues and What Happens Next
Despite the promising improvements, the rollout of KB5079391 was short-lived. Microsoft pulled the update on March 27, just one day after its release, citing undisclosed installation failures. The company has yet to provide a specific timeline for a revised version, leaving users waiting for the benefits of the update. However, Microsoft has assured users that the changes included in KB5079391 will be available in a future release, suggesting the issues are being addressed and a re-release is planned.
Users who did not install the update before it was withdrawn will automatically receive the corrected version when it becomes available through Windows Update. Microsoft typically tests updates extensively before widespread release, and the temporary removal of KB5079391 underscores the company’s commitment to delivering a stable and reliable user experience. The update applies to Windows 11 versions 25H2, 24H2, and 26H1.
The temporary setback with KB5079391 doesn’t diminish the significance of the increased refresh rate support. It’s a clear indication that Microsoft is actively investing in technologies that will enhance the PC gaming experience and prepare Windows 11 for the displays of tomorrow. The next step will be the re-release of the update, followed by continued refinement and optimization as higher refresh rate displays develop into more prevalent.
