Windows 7 updates KB4499164, KB4499175 issues

The May 2019 Patch Tuesday updates for Windows 7 PCs are not playing well with some third-party antivirus solutions.

We all remember the time when Windows 10 updates messed up third-party antivirus programs. However, the bug is back again to target Windows 7 devices.

Sophos recently released a security alert that warns users about the issues created by KB4499164 and KB4499175. Microsoft rolled out both of these updates on Patch Tuesday.

Users who are running Sophos Central Endpoint Standard/Advanced and Sophos Endpoint Security and Control on Windows Server 2008 R2 or Windows 7 machines are the ones most affected by this problem. 

The UK based security company Sophos explains that:

We have had a few customers reporting that following on from the Microsoft Windows 14th May patches they are experiencing a hang on boot where the machines appear to get stuck on ‘Configuring 30 percent’. 

The company confirmed that it is collaborating with Microsoft to fix the bug. Surprisingly, Microsoft didn’t acknowledge the bug on their KB page.

It seems that two of these updates are causing issues for Avira, Sophos, Avast, and ArcaBit.

Avast users are reporting that the latest round of updates are affecting Windows 7 machines with a free version of Avast antivirus programs. 

It is interesting to see how Microsoft is going to address these security issues. This may turn out to be a major setback for the tech giant who is already dealing with Windows 10 May 2019 Update bugs.
