Windows Admin Center v2606

Windows Admin Center (WAC) version 2606 is now Generally Available (GA). Unlike the milestone-heavy 2511, this is a quality-focused release: it consolidates reliability, accessibility, and security improvements driven by customer feedback and development-partner reports. It is also an Administration Mode release only — Virtualization Mode (vMode) remains a separate install and continues its own public preview track. Read on to learn about the new features and updates!

Platform updates

The platform receives a round of fixes aimed at smoothing out installation and gateway configuration:

• Resolved an installer error where standalone machines running a non-English OS incorrectly reported that high availability installations were not supported.
• Fixed the inability to add Allowed Groups containing spaces in the Access tab of gateway settings.
• Hardened the overall security posture.
• Addressed major accessibility issues, with improvements to keyboard navigation, dialog accessibility, screen reader support, and ARIA compliance across key management experiences. Common workflows are now easier to navigate with assistive technologies, improving compliance with accessibility standards.

Core tools and extensions

Several core tools and bundled extensions have been refined:

• The GPU tool is now available for Windows Server 2025 Standard edition.
• Fixed a volume-deletion issue present in Cluster Manager extension versions earlier than 5.2.6.
• Corrected scheduled task status not updating after a task was started.
• Import VM workflow: added a network summary to the review tab, and fixed the VHD destination, the Storage Summary, and the VM name not displaying correctly in the review tab.
• Fixed copying a physical hard disk in virtual machine settings.
• Raised the maximum network adapter limit for Gen2 virtual machines from 8 to 64 (Gen1 remains capped at 8).
• Updated Secure Boot logic and status messaging in the Security tool with clearer next steps.
• Improved error handling across the platform and tools including Files & file shares, Processes, Virtual machines, and Services.

Software-defined networking (SDN)

SDN management gets meaningful guardrails and bug fixes across virtual networks, gateways, and logical networks:

• Virtual networks: deletion of virtual networks — and deletion or editing of virtual subnets in use by virtual gateways — is now blocked, preventing the accidental modifications that previously led to failed provisioning states. Removal of Network Security Groups (NSG) from a virtual subnet resource is now allowed.
• Virtual gateway: a host IP form field was added to support a fix in the L3 fast path feature, and users can now set the unit of measurement for bandwidth allocation.
• Logical networks: a fix now allows updating logical networks with default network policies (no address prefix).

Partner ecosystem

Two development partners refreshed their extensions for this release.

The Dell OpenManage Integration extension was upgraded to version 3.6.0, adding configurable hardware alert polling and severity thresholds, WDAC support on Windows Server 2025, custom iDRAC alert configuration at cluster or node level, more accurate warranty reporting, clearer Azure policy onboarding when quota limits are hit, more reliable BitLocker handling during updates and cluster expansion, support for the Multi Cloud (APEX MC) platform on Azure Local, the new PowerEdge 17G models R7725xd and R770AP, and IPv6 connectivity to iDRAC over the Remote NDIS adapter. AX 16G clusters now also support mixed processor generations, running Sapphire Rapids and Emerald Rapids nodes together.

The Fujitsu ServerView Health and ServerView RAID extensions have been rebranded to FSAS Technologies ServerView Health and FSAS Technologies ServerView RAID, both upgraded to Angular 15.
