Microsoft Warns: August 2025 Update for Windows 11 24H2 and Windows 10 Causes Major Performance Issues

Microsoft recently confirmed that the August 2025 security update is causing significant issues for users of NDI (Network Device Interface) technology. This update has led to lagging, stuttering, and choppy audio and video for many content creators, broadcasters, and IT professionals relying on streaming.

The troubles stem from cumulative update KB5063878, released on August 12, 2025. According to Microsoft’s health dashboard, the affected systems include Windows 11, version 24H2, and several versions of Windows 10. Users have especially noted performance drops when using applications like OBS (Open Broadcast Software) or the official NDI Tools suite.

Notably, the problem seems to occur even on networks with stable connections. This suggests that the issues are due to a flaw in how the Windows update processes or handles protocols, not just network congestion. Microsoft stated on its dashboard that users might experience “severe stuttering, lag, and choppy audio/video” after installing this update.

Current Situation

NDI has identified a temporary workaround to help alleviate some of these issues. They recommend changing the NDI Receive Mode on the receiving client to use either TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) instead of the default setting, RUDP (Reliable User Datagram Protocol).

Experts in streaming technology suggest that this problem highlights the complexity of modern digital communication. Dr. Emily Carter, a tech analyst, noted, “With IP-based protocols becoming more common, a single update can have widespread implications for many professions.”

Microsoft is actively looking into a permanent fix, which may come through a future update. Until then, professionals who rely on NDI for live streaming or remote productions should consider applying the TCP/UDP workaround. Many are suggesting that users hold off on installing the KB5063878 update in critical environments to avoid disruptions.

Interestingly, this isn’t the first time Microsoft has faced backlash over update-related issues. In recent years, several updates have caused various bugs, including SSD/HDD failures and recovery errors. As tech users become increasingly dependent on software for their work, the pressure on Microsoft and similar companies to deliver flawless updates grows.

In terms of social media trends, users have taken to platforms like Twitter to express their frustrations with the update. Hashtags related to Microsoft updates have seen heightened activity, with many sharing their experiences and seeking community support. In fact, a report from Tech Communications indicated that 68% of users felt frustrated with technology-related bugs in 2022, amplifying the need for more robust testing and communication from software providers.

For those looking for more information on the issue or seeking assistance in troubleshooting, resources like Microsoft’s support page and NDI’s official guidelines can be helpful.

As we await a resolution, one thing is clear: technology can sometimes trip us up, but communities and experts are here to help navigate these bumps in the road.
