As administrators utilize Azure Virtual Desktop (AVD) with Windows 11 migration, a recent update to Windows 11, version 24H2, introduces an issue where the App-Attach feature fails to function properly. This problem specifically affects users of AVD who rely on applications packaged in the Composite Image File System (CIMFS). Microsoft has acknowledged this issue and released a fix that is gradually being rolled out through updates such as KB5060829, which became available on June 26, 2025. This update aims to resolve the problem and improve overall system performance.
The App-Attach feature in AVD allows dynamic attachment of applications from an application package to a user session without local installation on session hosts or virtual machines. When attempting to launch such applications, users may encounter errors like «element not found,» which is exclusive to Windows 11 24H2 running within Azure Virtual Desktop. Microsoft’s documentation outlines that only systems with App Attach applications packaged in CIMFS format are affected.
Microsoft recommends installing the latest updates to address this issue and other improvements and bug fixes included within them. For users who have not yet installed KB5060829 or subsequent updates, a workaround involves using VHDX (Virtual Hard Disk v2) images instead of CIMFS for packaging files.
Understanding these developments is crucial for IT administrators managing AVD environments to ensure smooth operations and prevent potential disruptions caused by the App-Attach malfunction. Microsoft’s proactive approach in addressing this issue reflects its commitment to maintaining robust virtual desktop solutions, although some users may face temporary challenges until the full fix deployment is complete.
