Known Issues

1. After installing the Microsoft Windows security update KB5094126 (released June 2026) on Windows 11 24H2/25H2 multisession VDAs, audio volume in Citrix ICA sessions automatically resets to 0% and cannot be adjusted. Audio recording and playback devices may also fail to function correctly within the session. More information available on CTX696723.
2. Microsoft is transitioning from the Windows UEFI CA 2011 certificate to the newer Windows UEFI CA 2023 certificate, with the 2011 certificate expiring in 2026. After applying the June OS updates, Citrix MCS/PVS Machine Catalogs using a golden image signed with the 2023 certificate may fail to boot, showing a “No Boot Media” error on VDAs. Further details and guidance are available in the referenced CTX articles below.
