If your hardware vendor never released a BIOS with SMBIOS 2.7, you cannot force it. Consider using a hypervisor to expose SMBIOS 2.7 to guest VMs instead.
SMBIOS tables changed the System UUID or Product Name slightly. Fix: Re-enter your product key. For volume license systems, run slmgr /ato from an admin command prompt. smbios version 27 update new
Refined how x86-class CPUs report features via the CPUID instruction, including better mapping for L1, L2, and L3 caches. Why This Update Matters for Your System
Version 2.7 introduced several new SMBIOS structure types, including: Consider using a hypervisor to expose SMBIOS 2

With the recent rollout of across new motherboards, workstations, and server platforms, a significant shift has occurred. This update is not merely a revision number bump; it introduces new data structures, enhanced memory management descriptors, and crucial security flags that modern operating systems (Windows 11, Linux kernels 5.10+, and modern ESXi) now rely on. For volume license systems, run slmgr /ato from
Here are the headline additions in SMBIOS 2.7:
Individual RAM modules grew significantly during this generation, requiring deeper telemetry:
Before unpacking version 2.7, let’s clarify the acronym. stands for System Management BIOS . It defines data structures and access methods that allow operating systems, management software (like Dell OpenManage, HP Systems Insight Manager, or VMware vSphere), and diagnostic tools to retrieve hardware information without directly probing physical components.
