Microsoft Fixes RDP Disconnection Issues in Windows 11 with KB5053656 Update

Microsoft has just ironed out a major glitch that was causing Remote Desktop Protocol (RDP) connections to unexpectedly drop—a flaw that had many Windows users and IT professionals scratching their heads. In an update that mirrors Microsoft’s usual race to patch its software, the company released the KB5053656 preview update on Thursday to resolve persistent disconnection issues affecting Windows 11 24H2 systems and certain Remote Desktop Services (RDS) scenarios, particularly when dealing with legacy setups.

Overview: What’s Been Happening​

Since January 2025, Windows updates have been at the center of controversy due to a problematic behavior in Remote Desktop connections. Users have experienced RDP disconnections after a mere 65 seconds when UDP connections are initiated from Windows 11 24H2 to servers running older versions—specifically those using Windows Server 2016 and earlier. This isn’t just an isolated incident. Microsoft noted that while Windows Server 2025 devices aren’t directly impacted when serving as RDS hosts, they too can fall prey to these sudden disconnects if used as RDP clients connecting to older servers.
Highlighting the urgency, Microsoft’s Windows release health dashboard pointed out that both the January 2025 Windows preview update (KB5050094) and subsequent releases were linked to these disruptions. The issue was exacerbated by the March 2025 Windows security update (KB5053598), which saw a notable spike in user complaints. For IT admins and end users alike, the frustration was mounting as critical remote connectivity, an essential service for many organizations, was compromised.

Delving Into the Remote Desktop Glitch​

Remote Desktop is a cornerstone feature for Windows administrators, allowing remote access to systems and servers across an enterprise. However, a bug in recent Windows updates meant that users attempting to establish a session via UDP experienced a forced disconnection just over a minute into the connection—65 seconds to be exact. Here’s a closer breakdown of the problem:

• Affected Systems: Windows 11 24H2 clients connecting to RDS hosts on older systems (e.g., Windows Server 2016).
• Connection Type: The issue specifically targets UDP connections, a method commonly employed to improve transmission speeds and reduce latency.
• User Experience: Even users with a stable network connection would suddenly find themselves logged off, leading to severed tasks and potential data loss.
• Enterprise Impact: Organizations that rely on remote connectivity for day-to-day operations faced interruptions, forcing IT teams to scramble for workarounds.

What made the issue even more complex was the fact that while Windows Server 2025 devices serving as RDS hosts were unaffected, when they acted as RDP clients connecting to older servers, similar disconnects were triggered. This nuance added an extra layer of unpredictability at a time when seamless remote operations are non-negotiable.

The Silver Lining: Microsoft’s Fix with KB5053656 Update​

After a spate of reports and mounting user feedback, Microsoft sprang into action. The KB5053656 preview update aims to rectify these Remote Desktop disconnects by addressing the underlying flaw in the handling of UDP sessions. Here’s what Windows users and IT managers need to know:

• Immediate Benefits: Installation of the KB5053656 update will stabilize RDP connections across affected environments, ensuring smooth and uninterrupted remote sessions.
• Rollout Strategy: Although the preview update has been released on Thursday, Microsoft plans for this fix to be included in next month’s cumulative updates, ensuring it reaches a broader audience.
• Enterprise Deployment: IT administrators can take advantage of the Known Issue Rollback group policy, allowing the fix to be deployed on enterprise-managed devices even before the broader rollout. This is especially beneficial for organizations that depend on remote connectivity for mission-critical operations.

This quick turnaround underscores Microsoft’s commitment to addressing issues that can impact productivity and security. It’s an essential reminder that while new features and security patches are crucial, they must not compromise core functionalities.

Stepping Through Troubleshooting: A Quick Guide for IT Admins​

It’s crucial for IT teams to balance prompt reinstallation of fixes with rigorous testing in non-production environments, ensuring that updates do not introduce unforeseen complications.

A Glimpse at Adjacent Remote Desktop and Connectivity Issues​

This isn’t the first time that Microsoft’s update process has been highlighted for its unintended consequences. Earlier in the week, another known issue came to light involving Remote Desktop freezes on Windows Server 2025 systems after installing security updates issued since the February 2025 Patch Tuesday. Although this particular issue on Windows 11 24H2 systems was largely resolved by the KB5052093 optional update released on February 25, Windows Server 2025 users may still see the fix rolled out through future updates.
Additionally, in related news, Veeam brought attention to an issue that has been causing connection errors. Windows 11 24H2 systems experienced difficulties when trying to restore data from Backup & Replication servers or SMB network shares—a problem that is currently under investigation by Microsoft. This multi-issue pattern underscores the challenges inherent in rapid update cycles where improvements in one area might inadvertently ripple adverse effects elsewhere.

The USB Printer Conundrum: More Than Just RDP​

While lots of our attention has been on Remote Desktop problems, Microsoft wasn’t done with troubleshooting. In a separate fix issued on Wednesday, the company resolved an equally perplexing bug affecting USB printers. Following updates released since late January 2025, affected devices would start printing random strings of text, a phenomenon that baffled many of our industry veterans. This fix, though less critical from a remote connectivity standpoint, represents Microsoft’s broader effort to refine and stabilize its operating system across all user scenarios.
