Microsoft finally released cumulative updates KB3176936 and KB3176934 to regular users of Windows 10 version 1607. As usual, these cumulative updates don’t bring any new features but instead focus on improving system stability.

However, besides system improvements and bug fixes, it looks like these two updates actually cause some issues of their own. Users have already reported a series of problems, allegedly caused by KB3176936 and KB3176934. We’re going to tell you more about all these reported issues, so that you know what to expect from these two cumulative updates.

Cumulative updates KB3176936 and KB3176934 reported issues

The first reported problem we stumbled upon is actually the most common problem in all Windows 10 updates whether they’re  builds, cumulative updates, or major updates. You guessed it: KB3176936 and KB3176934 fail to install on some computers. Here’s what one user said on Microsoft’s forums:

“A few minutes ago, Windows downloaded and installed some updates. All went fine, except for KB3176934 (one of updates named 1607).
I tried various times. It downloads the update, install it, but after the restart it figures like “failed””

One of the forum moderators offered a few solutions for this problem, and the user who first reported this issue said that one of the solutions worked without specifying which one. So, if you encounter installation problems with these two updates, check out this post on Microsoft’s forums and try the solutions mentioned there.

It appears that the KB3176936 and KB3176934 updates also break PowerShell. Microsoft is aware of this problem, and the company actually advised users who are experiencing PowerShell issues to avoid both updates:

“Due to a missing .MOF file in the build package, the update breaks DSC. All DSC operations will result in an “Invalid Property” error. If you are using DSC from or on any Windows client, take the following steps:

1. Uninstall the update if already installed…

2. If using WSUS, do not approve the update. Otherwise, Use Group Policy to set the ‘Configure Automatic Updates’ to ‘2 — Notify for download and notify for install’… A fix for this issue will be included in the next Windows update which is due out 8/30/2016.”

If you’re not familiar with the term, DSC is PowerShell’s Desired State Configuration, a set of extensions that gives admins control over computers.

That’s about it for the fresh problems caused by the cumulative updates KB3176936 and KB3176934, but there are some bigger problems that remain unsolved even after installing these updates. The system freezing issue reported ever since the Anniversary Update’s release is still present. Here’s what Reddit users say about these issues:

The external hard drive issue is still here. Namely, the system fails to recognize the external hard drive for some users after installing the Anniversary Update. Here’s what users say on Microsoft’s forums:

“For your information: with these new windows updates yesterday (KB3176934 and KB3176936) and after testing myself – the problem with the external HDs recognized as RAW is NOT fixed”

So far, Microsoft has said nothing about these two issues, and we don’t know when the company will be able to solve them. All we know for sure is that the latest cumulative updates don’t get the job done.
