Windows Server vNext Preview Build 29574 introduces Quick Machine Recovery (QMR) to automatically address boot failures and expands network storage options with NVMe-over-Fabrics support. Microsoft has set Build 29531 as the new baseline, requiring users with older preview builds to perform a clean install to avoid breaking their environments. The release also enables ReFS Boot but warns that improper partition management could lead to systems being locked out, necessitating fresh installations. Additionally, there are potential licensing issues for Server Core environments, and users are advised to download the latest ISO directly while avoiding incremental upgrades
Windows Server vNext Preview Build 29574: Quick Recovery, NVMe-oF and Clean Install Warning
Windows Server vNext Preview Build 29574 introduces Quick Machine Recovery to automatically fix boot failures and expands network storage options with NVMe-over-Fabrics support over TCP and RDMA. Microsoft has established a hard baseline at Build 29531, meaning anyone running an older preview must perform a clean install since incremental upgrades will likely break VMs and clusters. The update also enables ReFS Boot but warns that manually deleting or resizing the WinRE partition can permanently lock users out without a fresh installation. Server Core environments may face minor AppCompat FOD licensing issues after upgrade, so testers should download the latest ISO directly and avoid attempting any incremental updates.
