Microsoft has just acknowledged two more issues in the January 2019 monthly rollup for Windows 7, pushed to devices as update KB4480970.
Originally, the official KB page only pointed to a single bug in this update and potentially causing a network connection loss, but in an update posted today, the software giant says it’s now aware of two more issues.
First and foremost, Microsoft says that update KB4480970 could cause activation issues on a number of Windows 7 computers.
“After installing this update, some users are reporting the KMS Activation error, “Not Genuine”, 0xc004f200 on Windows 7 devices,” it says.
The bug is already being looked into, the company adds, and more information on this will be provided when it is available. No ETA has been provided.
Fixes already in the works
A second bug affects remote access to shares on both Windows 7 and Windows Server 2008 R2. I’ve seen users complaining of this problem on TechNet as well, and Microsoft recommends using a local account that is not included in the Administrators group or a domain user.
“Local users who are part of the local “Administrators“ group may not be able to remotely access shares on Windows Server 2008 R2 and Windows 7 machines after installing the January 8th, 2019 security updates. This does not affect domain accounts in the local "Administrators" group,” the company explains.
In this case, a fix is already under development, but Microsoft notes that it would only be included in a future release. This most likely means it would be published as part of the February 2019 Patch Tuesday cycle when new monthly rollups are expected. The next patch Tuesday takes place on February 12.
Microsoft will also release previews of its next monthly rollups later this month, but it remains to be seen if a fix for these issues would be included as well.
