This article applies to volume-licensed Windows 7 devices that use Key Management Service (KMS) activation and have the KB 971033 update installed. Some users may receive the Windows Activation or "Windows is not genuine" notifications starting at or after 10:00 UTC, January 8, 2019.
On January 9, 2019, we reverted a change that was made to Microsoft Activation and Validation servers. For devices that continue to report activation and “not genuine” notifications, you should remove KB 971033 by following the steps in the "Resolution" section.
Windows editions that support volume-licensing activation include the following:
- Windows 7 Professional
- Windows 7 Professional N
- Windows 7 Professional E
- Windows 7 Enterprise
- Windows 7 Enterprise N
- Windows 7 Enterprise E
For Windows editions that experience activation and “not genuine” errors that are not caused by the Microsoft Activation and Validation server change around January 8, 2019, we recommend that you follow standard activation troubleshooting.
