Error 0x80041008 hits SLMGR and automated KMS setup; devices already activated are expected to stay activated.

Microsoft confirmed that this month’s Patch Tuesday updates can cause Windows activation and licensing failures with error 0x80041008. The issue affects organizations that automate activation or use SLMGR on listed Windows 10, Windows 11, and Windows Server releases. Failures follow specific SLMGR domain and product-key commands, while images that already have the KMS client key and do not use those commands are not expected to be affected. Microsoft says a fix is coming within days and points urgent cases to Microsoft Support for business.

Unconfirmed: Microsoft has not published the fix date beyond saying it will arrive over the coming days.

Key facts
  • Affected clients are Windows 10 21H2/22H2 and Windows 11 23H2.
  • Affected servers are Windows Server 2019, 2022, and 2025.
  • Failing commands are slmgr.vbs /skms-domain and slmgr.vbs /ipk.
  • KMS-activated devices typically remain activated for up to 180 days.
