Overview

Microsoft has confirmed that its November security updates are causing activation and licensing failures with error codes 0x80041008 and 0x80041008. This issue affects organizations that automate Windows activation and licensing processes or use the Software Licensing Management Tool (SLMGR) command-line tool. Affected devices might encounter errors when running commands to activate Windows, configure Key Management Service (KMS), or manage product keys. Devices that are being configured to use KMS activation might encounter errors when attempting to initiate their activation. KMS-activated devices typically remain activated for up to 180 days following successful activation. The activation failures occur after executing the 'slmgr.vbs /skms-domain' and 'slmgr.vbs /ipk' commands on client and server devices. However, customers with the KMS client key installed in their image and who don't use SLMGR for licensing management are unaffected. A fix will be available over the coming days, and Microsoft advises affected organizations to reach out to Microsoft Support for immediate mitigation. In January, Microsoft addressed another known issue that was causing Windows license migration failures during upgrades because affected devices couldn't register with the Windows Activation server for digital licenses.
