The build number 26100 suggests this is a post-RTM candidate or a cumulative update build. Historically, Windows Server builds share the same core kernel as the corresponding Windows client. Build 26100 would likely align with Windows 11 version 24H2 (2024 Update). The .1742 suffix indicates the specific cumulative update (CU) applied — likely a preview or security update. This build is more advanced than early betas but may not yet be the final RTM.

AD has received its biggest upgrade in years with a new 32k database page size (up from 8k). This allows for much larger objects and better performance in complex environments.

The 26100.1742 build is the General Availability (GA) version. This build is the stable "gold" version, meaning it has passed the highest level of Microsoft quality assurance and is ready for deployment in production environments.

The rollout of Build 26100.1742 solidifies severe structural performance and storage upgrades, distinguishing it from legacy distributions like Windows Server 2022.
