Once again, Microsoft has released patches and updates that have broken parts of Windows.
Now, with the monthly rollup Windows 7 KB4480970, and security-only update KB4480960 flags some PCs as ‘Not genuine’. These niggles often trouble the users and the administrators in case of companies. It has recently come to the notice that Microsoft’s KB971033 update for Windows 7, the one released on January 2019 Patch day is causing some networking issues.
In some cases, even thousands of PCs were no longer activated. Quick determined the problem appears to have started after installing KB971033 in a monthly roll-up.
Those particular machines belonging to Microsoft license based KMS (Key Management Service) activation that allows an admin to activate many PCs conveniently by having them check in with a local server for a valid volume license key.
When a Windows 7 PC checked into the KMS server, the server sent a blacklisted error instead of the usual response, and this resulted in a “not genuine” message or the error code 0xc004f200.
The company advised, "we strongly recommend that you uninstall KB971033 from all volume-licensed Windows 7-based devices."
The firm also says that KB971033, an old update, should not have been installed by an Enterprise customer who uses Key Management Service or Multiple Activation Key (MAK) volume activations, as it was targeted at consumer installs of Windows using retail activation.
The update was originally released on April 2018 as part of the Activation Technologies of Windows 7 Home Basic, Home Premium, Ultimate and professional.
These updates have been associated with a separate bug that blocks administrator access to remote shares on Windows Server 2008 R2 and Windows 7.
The software giant assured that the company is working on a solution; it is working to fix and everything should be back to normal soon.
