This week, Microsoft pushed out another cumulative update and reports of installation problems are widespread. While I don’t know how many users are impacted, based on comments sent to me, it’s certainly widespread enough that this is well beyond an isolated issue.
The update that is causing the problem, KB3194496, is not installing correctly for users. The update, when it does fail, is causing some machines to restart, often multiple times, as Windows 10 attempts to remove the failed update. Worse, after a restart, the file will attempt to install again resulting in the loop of failed install, reboot, re-install and failure again.
Some users have reported that the cumulative update did install correctly on the second or third attempt while others have said that it fails every time.
As you can imagine, having this happen to your machine is not a fun experience but what is perplexing about this is that the issue was reported by those who are in the ‘release preview’ ring ahead of the wider-scale release; we know this as it was reported in the Microsoft’s support forums. If the bug was reported, why did Microsoft go ahead and release the patch if the feedback indicated there was an issue?
I would bet that Microsoft will say that the telemetry suggested that for most users, the update installs correctly. But, seeing how many reports are being mentioned on Twitter and andre steder, it’s clear that a significant number of users are impacted.
If you do have this problem, there isn’t a workaround at this time but if you do find a solution to update problem, make sure to let us know so we can pass it on to those who are impacted by this bug.
Microsoft is pushing the idea that you should always patch your machine on the day the update is released as they often release security patches that fix vulnerabilities. But, until the company can get a handle on their quality control issues, such as the Anniversary update breaking millions of webcams, it feels like every time you run Windows update you are rolling the dice.
