Microsoft still not said anything about unexpected Windows Server 2025 installs
Microsoft remains silent over Windows Server 2025 turning up in the guise of a security update earlier this week, much to the chagrin of affected administrators.
On November 5, Microsoft seemingly mislabeled the Windows Server 2025 upgrade with a globally unique identifier (GUID) for updates. The result was that some administrators' were faced with a surprise install of Windows Server 2025 thanks to patching software downloading and installing what was tagged as an update but instead turned out to be a whole new operating system.
The erroneous labeling itself was not enough to trigger an installation. However, some deployments of third party patching software misclassified it and applied it to servers. The problem was initially noted by a customer of security business Heimdal who arrived in the office to find Windows Server 2025 unexpectedly on their hardware.
Morten Kjaersgaard, chairman and founder of Heimdal, told The Register: "We noticed that the Microsoft Server 2025 migration is automatic, which is mindbogglingly dangerous given the operational risk for customers facing unexpected downtime.
