What about “Server 2025”?
Microsoft has been testing a “vNext” release internally, sometimes referred to as Windows Server 2025 or 2026 by enthusiasts. However, no public RTM (Release to Manufacturing) exists. The only legitimate way to test future server versions is via: Windows Server 2025.26100.1742-OEMRET-x64FRE-en...
If you see build 26100.1742 in a server context, it is almost certainly a Windows 11 24H2 client OS mislabeled or repurposed.
The file identifier Windows Server 2025.26100.1742-OEMRET-x64FRE-en represents a specific, likely legitimate snapshot of Microsoft’s upcoming server OS, tailored for OEM recovery scenarios. While it offers a glimpse into the future of enterprise server features—including advanced security, storage, and hybrid capabilities—IT administrators should treat it with caution unless obtained directly from an authorized hardware partner or Microsoft’s official evaluation program.
For production deployment, wait for the final RTM build. For testing driver compatibility, recovery image validation, or learning the new administrative workflows, this build provides a stable enough environment, provided you respect licensing constraints and update it immediately to the latest cumulative update after installation.
Key takeaway: Always verify hash values (SHA-256) of any OEMRET image against the hardware vendor’s provided checksum to avoid tampered or malicious versions.
