About this tag
The kb5059091 tag covers emergency out-of-band (OOB) Windows Server updates released by Microsoft to fix a container launch failure issue. The problem affected Windows containers running under Hyper-V isolation mode, introduced by the 2025.04 B container images from April 8, 2025. When the update level of the container did not match the host's utility virtual machine (UVM), compatibility problems prevented containers from starting. The updates resolve system file mismatches that disrupted Windows Server 2025 and other affected versions. IT administrators should apply these updates to restore container functionality and avoid cryptic error messages.
