About this tag
Windows Deployment Services (WDS) is a network-based provisioning role used by enterprises to PXE-boot target machines and deploy Windows images at scale. Recent discussions on WindowsForum.com focus on a significant security hardening initiative by Microsoft, beginning with the January 2026 cumulative update KB5074109. This update addresses CVE-2026-0386, an improper access control vulnerability that could allow remote code execution by an unauthenticated actor on an adjacent network. The hardening plan phases out the insecure delivery of Unattend.xml answer files during hands-free imaging, with the legacy behavior blocked by default in April 2026 unless administrators explicitly re-enable it. Administrators must update deployment workflows to maintain security compliance.
