====================
Update: 5th April 2018:
====================
On the 3rd of April, Microsoft released an out of band security update for the Microsoft Malware Protection Protection Engine. Further details are available in this separate blog post.
====================
Separately Microsoft have since issued an update, KB4099950 to resolve the issue detailed below affecting the network adapter on Windows 7.
The new update KB4099950 must be installed before KB4088875 and KB4088878 (I assume if this is not the case that KB4088875 and KB4088878 could be uninstalled first?)
If you were experiencing any of the following issues on Windows 7 or Windows Server 2008 R2, please install the above update to resolve them:
====================
A new Ethernet Network Interface Card (NIC) that has default settings may replace the previous NIC and cause network issues.
Static IP address setting are lost.
These symptoms may occur on both physical computers and virtual machine that are running VMware.
====================
Thank you.
====================
Update: 1st April 2018:
====================
Microsoft have issued an out of band update for Windows 7 SP1 64 bit and Windows Server 2008 R2 SP1 64 bit to resolve resolve a regression (an un-intentional coding error resulting in a previously working software feature no longer working, alternative definition here) which introduced an additional elevation of privilege (defined) security vulnerability in the kernel (defined) of these Windows version, please see my new post for further details.
This post has also been updated with further software releases (please see below).
If you have already checked for updates and are not seeing any being offered for your Windows 7 or Windows 8.1 system, please ensure your anti-malware software is up to date. This article explains why this change was implemented by Microsoft. It also provides recommendations of how to resolve the issue of no updates being available. Windows 10 is not affected by this issue.
A known issue of a second network adapter appearing within Windows 7 has also been documented. If this occurs for you with March’s updates, this news article may be of assistance in resolving it. It is anticipated that Microsoft will resolve this issue in this month’s upcoming security updates.
Thank you.
