General Availability of Windows Server 2025 Announced by Microsoft

Today marks a significant milestone as Microsoft has officially launched the general availability (G.A.) of Windows Server 2025, commencing with build 26100.1742. This latest iteration of the Server operating system falls under the Long-Term Servicing Channel (LTSC), providing nearly a decade of extended support until October 10, 2034, while mainstream support will continue until October 9, 2029.

Features and Enhancements in Windows Server 2025

In a detailed announcement, Microsoft highlights that Windows Server 2025 is not just another OS release but an advanced platform enhanced with security features and remarkable hybrid cloud capabilities. This release signifies a high-performing, AI-capable environment tailored for evolving business needs.

According to Microsoft, “Windows Server 2025 represents a leap forward in terms of performance and hybrid cloud integration.”

Key technical improvements include substantial advancements in I/O throughput performance, which Microsoft has elaborated on in follow-up communications. Enhancement efforts have also been directed toward GPU virtualization, notably through features like GPU Partitioning and Multi-Instance GPU, as well as Virtualization-Based Security (VBS) enclaves, which improve overall system security and performance.

Update Mechanisms and Known Issues

Windows Server 2025 is set to receive updates through a new mechanism termed checkpoint cumulatives, similar to how updates are delivered for Windows 11 24H2. However, users should be aware of three known issues that have come to light:

• Some text may display in English during installation.
• Performance may be suboptimal on devices equipped with high-core count CPUs.
• Users might encounter a ‘boot device inaccessible’ error in iSCSI environments.

For those facing the high core count issue, Microsoft recommends a workaround by limiting the core count to 256 or fewer to ensure optimal performance.

Accessing Windows Server 2025

If you’re eager to explore Windows Server 2025, a 180-day free trial is available for download from the Evaluation Center on Microsoft’s official website.
