The month of update bugs

This month seems to have become the month of update bugs. First, we have a Windows 10 update that will cause random freeze ups of the computer. I have been experienced this one on my own workstation. At first I thought I might have some sort of hardware issue, but Microsoft recently announced that the issue was being caused by a recent update. Unfortunately, we can’t just stop getting updates because 90% of the updates are security related and over half are addressing an active exploit currently being utilized by bad actors on the internet. So it’s far better just to deal with any hiccups that come with updates and follow guidance from those who created the bug in the first place.

There are many many reasons that a PC can freeze, spontaneously reboot, generate a blue screen error, etc. So do not assume that this recent potential cause is what is going on with your machine specifically. However, from what I have come to understand patch KB4493509 can not play nice with some third party security/antivirus applications. This comes as somewhat not a surprise since Microsoft has been hard at work behind the scene altering Windows 10 under the hood when it comes to the antivirus and software based firewall side of things. The previous two builds of Windows 10, build 1809 and 1803 both had issues with the vast majority of third party antivirus programs that required all antivirus makers to rewrite code in order to comply with Microsoft’s requirements.

So basically, we are probably still shaking the bugs out of those changes and both Micrsoft and antivirus vendors are still working on how to play nice with each other under the new security features of Windows 10 builds 1803 and 1809. Case in point, our very own self branded security software based upon Comodo Advanced Endpoint Protection version 11.2.0.7313, had a recent hiccup/conflict/dog fight with Windows 10’s firewall settings in its most recent version which Comodo yanked as soon as they became aware of the issue and immediately sent out a notification to all of us Manged Service Providers. I got the notification shortly after the first few endpoints began exhibiting weird issues with dropping off and on the network. We had to systematically go through last Friday and deploy an override profile onto all the endpoints that we manage that had already upgraded to the latest version of the security client so that a simple reboot would fix the firewall issue. It was less than 50 endpoints effected. My own workstation was effected by this.

The ironic thing is that this was also shortly after I just resolved a similar network issue with my own workstation involving our 3CX VoIP phone system which also released a new version of their software in the past few weeks. In the case of 3CX, all Grandstream branded VoIP phones began shutting down the PC port on the back of the phones as the default setting after receiving a firmware update while on the 3CX phone system. 3CX worked with Grandstream and got a new template created for the Grandstream phones that resolved that issue but it took some serious Googling for us to discover this issue was related to the 3CX upgrade.

Not to be outdone though, we had one or two customers who use some third party cloud based software that informed us that their third party software vendors had released updates that disrupted things for a bit. So even with a cloud based app, every now and then a bug will creep through with recent updates that doesn’t even have anything to do with what OS or other apps you happen to be running….lol Fortunately, from the sounds of things, they were just as quick as Microsoft and Comodo to identify and begin addressing their bugs.

Fact is, software updates are a fact of and necessity of life in the Internet of Things world we live in now if we wish to remain reasonably secure from malcious actors. There’s simply no turning back without pulling the plug and going Amish. So it’s the job of people like us to help identify, work around and eventually apply provided fixes for said bugs when they do hit after a recent update. And yes, Windows isn’t the only platform that has had recent bugs pop up after recent updates.
