Microsoft’s recent announcement of Windows 11 24H2 reaching “broad availability” should by all accounts be a momentous event for the Windows ecosystem. The company’s latest feature update, now being pushed out to eligible users across the globe, embodies the characteristic ambitions and paradoxes of the modern Windows development cycle: aggressive innovation paired with iterative problem-solving, mass deployment followed by a growing list of “known issues.” With the Windows Health Dashboard now flagging a fresh bug impacting Azure Virtual Desktop (AVD) users leveraging the App attach feature, the narrative around Windows 11 24H2’s rollout is once again a careful balance of progress and caution. This article examines the 24H2 launch, Microsoft’s evolving cloud-first strategy, and the intricacies surrounding the newly disclosed AVD issue.
With Windows 11 24H2, Microsoft has reached what it calls the “last phase of the gradual rollout” via Windows Update. The update is now classified as “broadly available,” meaning it’s actively being delivered as an automatic update to all supported Home and Pro devices running Windows 11 versions 22H2 and 23H2, unless managed by organizational IT policies. Devices that have compatible hardware and do not defer updates through group or local policy have either already begun receiving 24H2 or will do so imminently.
Users are theoretically empowered by update management options: they can schedule the necessary restart, or choose to delay installation—a safeguard intended to soften the disruption from major Windows updates. Such workflows, familiar to Windows veterans, emphasize Microsoft’s continued commitment to balancing user autonomy with system security and up-to-dateness.
From a feature perspective, 24H2 promises a bevy of improvements, including performance gains, new AI-powered experiences (leveraging Copilot integrations), security enhancements, and further refinements to system usability. Microsoft’s own communications have highlighted advances in efficiency, system stability, and modernization aimed at supporting emerging hardware—especially as AI PCs become mainstream.
Microsoft recommended CimFS specifically for cases where session hosts are running Windows 11, highlighting its improved performance for mounting and unmounting application images.
The immediate workaround? Microsoft instructs users to package application images using VHDX instead of CimFS for the time being. It is not the elegant resolution many enterprise IT teams had hoped for, especially considering VHDX does not offer the same theoretical speed benefits as CimFS.
A formal fix, according to Microsoft, isn’t expected before June 2025—a considerable delay given the significance of AVD in many organizations’ cloud strategies.
Cloud-based desktops and app streaming have become central to Microsoft’s vision for enterprise computing. The reliability of features like App attach is foundational for organizations seeking to shift away from traditional, device-tethered app deployment.
It’s a familiar tradeoff for those invested in the cutting edge of Windows: early access to powerful new features, balanced against the risk of operational headaches and the need for interim workarounds.
Yet, the velocity of change brings operational challenges, especially when cloud and virtual infrastructure is involved. For many users and organizations, a calculated delay—allowing time for initial issue resolution—is likely wise, especially as the known issues list continues to grow.
In the interim, IT departments should heed Microsoft’s mitigation guidance, deploy updates judiciously, and maintain rigorous compatibility testing—especially in environments with complex app delivery requirements or significant reliance on Azure Virtual Desktop.
As the update rolls out, judicious users will strike a balance between embracing Microsoft’s cloud-first future and keeping both eyes on the growing “known issues” list—recognizing that, as ever, the progress of technology marches hand-in-hand with a persistent need for patience and preparedness.
Windows 11 24H2: A Major Update Hits the Masses
With Windows 11 24H2, Microsoft has reached what it calls the “last phase of the gradual rollout” via Windows Update.

The Azure Virtual Desktop “App Attach” Issue: What Went Wrong
Yet, as is becoming tradition, Microsoft’s victory lap is cut short by a newly documented problem flagged on the same day the update was declared “broadly available.” The latest addition to the “known issues” list centers on the Azure Virtual Desktop (AVD) App attach feature—a tool designed to simplify enterprise app delivery.Understanding App Attach and Its Promise
App attach enables virtual applications to be dynamically “attached” to user sessions in Azure Virtual Desktop environments. Rather than being statically installed on every session host, application packages can be distributed in formats such as VHD (Virtual Hard Disk), VHDX (its v2 update), or Composite Image File System (CimFS). This flexibility allows for leaner master images, faster provisioning, and easier updates—core requirements for efficient cloud VDI (Virtual Desktop Infrastructure).Microsoft recommended CimFS specifically for cases where session hosts are running Windows 11, highlighting its improved performance for mounting and unmounting application images.
The Bug: “Element Not Found”—And No Immediate Fix
The newly discovered bug is clear: users attempting to launch App attach applications packaged with CimFS images on Windows 11 24H2 are encountering a failure—specifically, an “Element not found” error. According to Microsoft, this issue does not affect earlier OS versions and is isolated to the CimFS application image path.The immediate workaround? Microsoft instructs users to package application images using VHDX instead of CimFS for the time being. It is not the elegant resolution many enterprise IT teams had hoped for, especially considering VHDX does not offer the same theoretical speed benefits as CimFS.
A formal fix, according to Microsoft, isn’t expected before June 2025—a considerable delay given the significance of AVD in many organizations’ cloud strategies.
Broader Implications: Cloud PC, Windows 365, and the Cloud-First Frontier
The timing of this AVD-based glitch is particularly awkward for Microsoft, which is ramping up promotion of the Windows 365 Cloud PC—a service built on technologies closely related to AVD. The Windows 365 Cloud PC essentially provides a persistent, always-available Windows environment in the cloud, leveraging much of the same virtualization and app delivery framework as AVD.Cloud-based desktops and app streaming have become central to Microsoft’s vision for enterprise computing. The reliability of features like App attach is foundational for organizations seeking to shift away from traditional, device-tethered app deployment.
