Some Windows 7 users cannot install the KB4100480 patch

In late March, Microsoft released the KB4100480 update for Windows 7 SP1 and Windows Server 2008 R2, mainly to further repair the Meltdown vulnerability announced in January of this year. Unfortunately, some users cannot install the update.

According to the latest report released by theregister, KB4100480 is displayed as “not applicable” on some Windows 7 devices, although this update is obviously compatible with the current device. A system administrator from the same source said: “The problem is that they’re showing as ‘not applicable’ for all but 4 of my 120 win7 x64 machines. So even though I’ve approved the update, it’s not getting applied to the machines that need it, because the ‘update needed’ detection appears to be buggy.”

In addition, users on the AskWoody website have the same complaints, and the same problems have occurred on Windows 7 and Windows Server 2008 R2.

A user wrote in the post: “We’re seeing similar issues with out WSUS environment. Of approximately 200 Win2008R2 systems all of which have installed more than at least one of the qualifying Jan-Mar updates only 18 are showing that KB4100480 is applicable.  On top of that, since we do utilize WSUS, nearly all of those 200 systems are patched identically. And there is a similar story with the Win7x64 systems”

There’s now a hot fix available for Windows 7 and Server 2008 R2 users who find the latest security updates knacker their networking settings.
