Microsoft has marked its problematic 2024 Windows Server 2025 forced upgrade incident as "resolved" more than a year later via cumulative update KB5082063. Administrators reported surprise overnight upgrades with no clear rollback path; Microsoft blamed third-party update tools, though some reports indicated affected servers without such tools.
