In a recent update to its Release Health Dashboard, Microsoft has acknowledged that certain instances of Windows Server 2019 and 2022 were inadvertently upgraded to Windows Server 2025. This unexpected transition has raised eyebrows among users and administrators alike.
Details of the Upgrade Incident
The tech giant explained that the automatic upgrades occurred in environments utilizing third-party products for client and server updates. Microsoft advised users to check their third-party update software configurations to ensure they are not set to deploy feature updates without explicit consent.
According to Microsoft, the Windows Server 2025 feature update was categorized as an Optional update, classified under the Upgrade Classification: ‘DeploymentAction=OptionalInstallation’. The company emphasized that feature update metadata should be interpreted as Optional rather than Recommended by patch management tools.
This clarification, however, contrasts with reports from some third-party vendors and system administrators. Cybersecurity firm Heimdal noted last week that the update had been misclassified, prompting Microsoft to retract it. Additionally, a reader from The Register recounted an incident where a standalone server, devoid of any third-party update services, experienced an unexpected overnight upgrade.
Critics have pointed out that including a feature that requires a licensing fee within an update channel raises concerns about transparency and user consent. Microsoft has described the situation as “mitigated,” yet it has not provided any tools to facilitate a rollback for affected users. Consequently, administrators may need to rely on backups or consider the financial implications of acquiring Windows Server 2025 licenses.
In a separate matter, Microsoft has indicated that another issue has been “resolved,” where an update to Windows Server 2025 was mistakenly presented via a banner in Windows Update. The company clarified that this message was intended for organizations looking to perform an in-place upgrade.
Microsoft is reportedly collaborating with third-party providers to enhance best practices and recommended procedures moving forward. As inquiries continue, both The Register and Heimdal have sought clarification from Microsoft regarding the availability of a rollback tool and the validity of the company’s explanations. Updates will be provided as responses are received.
