Introduction

Microsoft's recent announcement of Windows 11 24H2 reaching broad availability marks a significant milestone in the evolution of the Windows operating system. This update introduces a suite of new features aimed at enhancing user experience, security, and performance. However, the rollout has not been without its challenges, notably a critical issue affecting Azure Virtual Desktop (AVD) users utilizing the App Attach feature.

Key Features of Windows 11 24H2

Enhanced AI Integration

Windows 11 24H2 places a strong emphasis on artificial intelligence, introducing features designed to streamline workflows and improve productivity. The integration of AI-powered tools aims to provide users with more intuitive and responsive experiences.

Support for Wi-Fi 7 and Bluetooth LE Audio

The update brings support for Wi-Fi 7 (802.11be), offering faster data transfer speeds and improved connectivity. Additionally, Bluetooth LE Audio support enhances audio quality and energy efficiency for wireless devices.

HDR Background Support

Users with HDR monitors can now enjoy HDR background support, providing richer and more vibrant visuals on compatible displays.

Challenges and Known Issues

Despite the promising features, the 24H2 update has introduced several challenges:

Azure Virtual Desktop App Attach Bug

Issue:

After upgrading to Windows 11 24H2, AVD users utilizing the App Attach feature with applications packaged in Composite Image File System (CIMFS) format encounter an "Element not found" error when attempting to launch these applications. This issue does not affect applications packaged in Virtual Hard Disk v2 (VHDX) format.

Workaround:

Microsoft recommends repackaging applications using the VHDX format as a temporary solution. A permanent fix is anticipated in future updates.

Impact:

This bug poses significant challenges for organizations relying on AVD for remote work solutions, potentially disrupting workflows and necessitating additional resources to implement the workaround.

Other Notable Issues

  • AutoCAD 2022 Compatibility:

Users have reported that AutoCAD 2022 fails to open after installing the 24H2 update. Microsoft has applied a compatibility hold to prevent affected devices from updating until a resolution is available.

  • Dirac Audio Issues:

Devices with Dirac Audio technology may experience loss of audio output post-update. Affected devices will not receive the update until the issue is resolved.

  • Easy Anti-Cheat Conflicts:

Some devices using Easy Anti-Cheat may encounter blue screen errors. Microsoft is collaborating with Easy Anti-Cheat to address this incompatibility.

Implications for Enterprise IT

The challenges associated with the 24H2 update underscore the importance of thorough testing and validation before deploying major updates in enterprise environments. IT administrators should:

  • Monitor Official Channels:

Regularly check Microsoft's Windows Health Dashboard for updates on known issues and resolutions.

  • Implement Workarounds:

Apply recommended workarounds, such as repackaging applications in VHDX format for AVD, to mitigate disruptions.

  • Plan for Delays:

Anticipate potential delays in deploying the update across the organization due to compatibility issues.

Conclusion

While Windows 11 24H2 introduces valuable features that enhance the operating system's capabilities, the accompanying challenges highlight the complexities of large-scale software deployments. Organizations must balance the benefits of new features with the potential risks and ensure robust testing and contingency plans are in place to maintain operational continuity.
