Threat Score
Microsoft confirmed that the November 2025 non-security preview update KB5070311 (and subsequent patches) breaks RemoteApp streams in Azure Virtual Desktop for some Windows 11 (24H2/25H2) and Windows Server 2025 deployments, causing connection failures for published applications; Microsoft provided two mitigations (a registry change and an automated Known Issue Rollback with an MSI for managed environments) and plans a permanent fix in a future update.
