<p>Microsoft’s recent release of Windows Server 2025 introduced powerful features aimed at enhancing performance, particularly for AI tasks. Support for GPU partitioning is among its highlights. However, the rollout hasn’t gone smoothly, with some users encountering unexpected updates and technical issues.</p>

<p>Reports have surfaced, notably on Reddit’s r/sysadmin, of an unusual scenario where UK-based companies found their Windows Server 2022 systems upgraded to Windows Server 2025 without warning. The original post suggests that the KB5044284 “security update” may have been mislabeled by their patch management software, Heimdal, which flagged it as an “Operating System Update” and inadvertently pushed the upgrade.</p>
<p>One user questioned if Windows Server 2025 was being deployed similarly to typical Patch Tuesday updates or if the company missed an important setting. Others chimed in with similar experiences, noticing that the update classification varies. Some systems recognize it as a “feature” update, while others categorize it as a security update, depending on the Windows Server version.</p>
<p>The Windows Server 2025 launch has also faced technical hurdles. Microsoft has acknowledged at least three known issues: the display of English text during installation on non-English systems, a boot error in iSCSI environments, and compatibility problems with CPUs supporting over 256 threads. Systems with high-thread CPUs may experience prolonged installation, slow restart cycles, and even a blue screen of death (BSOD) under certain conditions.</p>
<p>For some administrators, the unanticipated upgrade and the bugs have turned Windows Server 2025’s launch into a complex challenge, raising questions about update processes and patch management accuracy.</p>
