This error appears during the Windows setup phase of the captured image and can interrupt automated deployment sequences, causing confusion for technicians performing image deployments. + +- **Windows 10 IoT Enterprise LTSC 2021 incorrectly reported as unsupported** + + Windows 10 IoT Enterprise LTSC 2021 (version 21H2, Build 19044) devices are incorrectly reported as "not supported" in the ConfigMgr console. In **Administration** > **Management Insights** > **Simplified Management** > **Update Clients to a supported Windows 10 version**, these devices show "Action needed". The Product Lifecycle dashboard also incorrectly shows these devices as end-of-life, even though Windows 10 IoT Enterprise LTSC 2021 has mainstream support until January 12, 2027. + +- **Software Center compliance check fails in co-managed environments** + + An internal service required for device compliance checks will be deprecated in October 2026. Following the deprecation, compliance checks in Software Center may fail in co-managed environments where the Compliance workload is managed by Intune. To prevent this issue, apply this update before October 2026. For more information, see [KB 37172183](../2503/37172183.md). + +- **Applications with OS requirements fail during OSD with HTTP 404 error after upgrading to 2509** + + After upgrading to ConfigMgr 2509, applications with OS requirement rules (such as "All x64 Windows 11 and higher Clients") fail to install during Task Sequence deployment. Multiple applications that reference the affected OS requirement fail simultaneously. Errors similar to the following are recorded in the CIDownloader.log file. + + ```text + failed to download source file http://mp/SMS_MP/.sms_dcm?Id&DocumentId=Windows/All_x64_Windows_11_and_higher_Clients/ to destination ... with error 0x80190194 + ``` + +- **Co-managed clients with 3rd party update catalogs receive updates from incorrect source** + + In ConfigMgr 2509, co-managed clients with third party update catalogs stop receiving updates from the expected source. The Windows Update Agent is locked to WSUS for Quality, Feature, and Driver updates even though the co-management slider is set to Intune. The `SetPolicyDrivenUpdateSourceForXXXUpdates` registry values for Feature, Driver, Quality updates under `HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate` are incorrectly assumed to be 1 (WSUS) if only the key `SetPolicyDrivenUpdateSourceForOtherUpdates` is set to 1 (making it a partial configuration of policy). This issue was originally addressed in [KB 36495448](../2509/36495448.md). + +- **ConfigMgr client upgrade fails on Windows 11 ARM64 devices** + + Client push installation (CcmSetup) fails with error code `0x80070643` on Windows 11 ARM64 devices when upgrading from ConfigMgr 2403 or 2503 to 2509. The failure occurs during the upgrade path when the installer attempts to uninstall a 32-bit Microsoft Policy Platform (MPP) component that doesn't exist on ARM64 architecture. The issue doesn't occur on x64 devices and reproduces on Windows 11 25H2 ARM64 and 26H1 ARM64. + +- **Subsequent ConfigMgr client upgrades fail on ARM64 after initial upgrade failure** + + On Windows 11 ARM64 devices, if a previous ConfigMgr client upgrade failed to uninstall the 32-bit Microsoft Policy Platform (MPP) MSI, subsequent client upgrades also fail with error code `0x80070643`. In ccmsetup.log, the 32-bit `MicrosoftPolicyPlatformSetup.msi` uninstall is attempted and the error is ignored, but the upgrade logic then proceeds to install the 64-bit MPP without checking whether it's already present, causing the `client.msi` upgrade to fail. + +- **Microsoft Defender does not apply Intune policies after Endpoint Protection workload is switched to Intune** + + When the Endpoint Protection (EP) co-management workload is switched from Configuration Manager to Intune, Microsoft Defender doesn't pick up Intune's Endpoint Protection settings. Defender remains in a state where it believes Configuration Manager is managing it. Intune AV policies (such as tamper protection) aren't applied. The issue occurs because the ConfigMgr client leaves behind a registry key that prevents Defender from recognizing the workload transition. + +- **Intune EDR policies fail to apply on tenant-attached clients** + + In ConfigMgr 2509, Intune Endpoint Detection and Response (EDR) policies fail to be applied on ConfigMgr clients via tenant attach (non-co-managed). The ConfigMgr client doesn't receive or process EDR policy from Intune when only tenant attach is configured without co-management. Policy deployment errors may appear in client logs related to EDR configuration. + +- **Security update for Configuration Manager** + + This update enhances security in Configuration Manager by improving access controls for the Network Access Account (NAA).
