Some Windows 7 admins are feeling the pain of Microsoft's latest updates in this week's Patch Tuesday releases. From a report: Users who've installed this Tuesday's KB4480970 cumulative January update have been complaining of network connectivity issues on those devices based on a network that uses the SMBv2 file sharing protocol. Microsoft released its update to fix several identified vulnerabilities, including a remote execution flaw in PowerShell and to add robustness against side-channel attacks like those targeting the Meltdown and Spectre flaws. But a number of users immediately complained of networking issues, with Microsoft confirming there are now three known problems with the January patch. The other issues comprise an authentication error, and a file-sharing issue affecting some user accounts. ZDNet adds: Regarding the 'Not Genuine' Windows 7 error, Microsoft confirms that "some users are reporting the KMS Activation error, 'Not Genuine', 0xc004f200 on Windows 7 devices". "We are aware of this incident and are presently investigating it. We will provide an update when available," writes Microsoft on both KB4480960 and KB4480970.
