Microsoft recently released a new cumulative update for Windows 10 version 1607. KB3194496 is just a regular update that brings some system improvements and bug fixes, but no new features.

However, cumulative update KB3194496 is also bringing issues of its own. In this article, we’re going to list all the KB3194496 issues reported by Windows 10 users, and we’ll try to find a way to solve at least some of them.

Windows 10 KB3194496 reported issues

The most widespread problem, and the issue most users are reporting, concerns, of course, installation problems. Microsoft Community forums are currently flooded with complaints, as many users are reporting various problems that prevent them from installing the update.

Tried half a dozen times to update Windows 10 14393.187 to 14393.222 on my Toshibia Satellite C655-S5339 laptop running Windows 10 Pro 14393.187. KB3194496 downloads and goes through preparing to install just fine. However,  Working on Updates goes up to 99% then shows: We couldn’t complete the updates
Undoing changes
Don’t turn off your computer
Upon rebooting and logging back in, Windows Event Viewer records the following in the system log:
Event 20, WindowsUpdateClient:
Installation Failure: Windows failed to install the following update with error 0x800F0922: Cumulative Update for Windows 10 Version 1607 for x-6-based Systems (KB3194496)

This surely is a very annoying problem, as it can completely block Windows Update, leaving users unable to download the cumulative update normally. However, there are a few actions that users can perform to install KB3194496 on their computers.

Users can manually reset Windows Update, use a third-party program to download updates, but perhaps the best solution in this case is to manually download and install the update.

Another issue when installing cumulative update KB3194496 concerns keyboard functionality. Namely, the problem occurs on the first boot after the update is installed. Windows 10 asks users to choose a keyboard layout, but the keyboard remains unresponsive.

So I have a friend who just finished installing the KB3194496 cumulative update for windows 10 a few hours ago. Window’s did it’s typical “Installing X%” and rebooted, but when it rebooted it was trying to do an automatic system repair. It then cuts immediately to a blue screen telling him to choose a keyboard layout, but he can’t use the mouse and the keyboard buttons don’t respond.

Unfortunately, no one replied to this report, so the solution for this problem is still unavailable. If this issue rings a bell to anyone, please let us know about the solution in the comment section below, in the case you found one. We’re sure many users will find it helpful.

And finally, another user reported Chrome and Firefox proxy authentication issues that, according to him, have been affecting the last three cumulative updates, including KB3194496:

Other people on the forum remained silent when it came to solving the problem, but one user actually explained what’s causing it:

I’m experiencing the same issue with a company proxy McAfee Web Gateway and a Windows 10 client, after the abovementioned update. I’ve traced the connection and discovered that the problem is related to Google Chrome not completing the 3-way handshake of NTLM authentication (in particular, step 3)

The issue is very weird considering that, from a comparison between MS Edge and Chrome, step 1 and 2 are the same. Then Edge completes the procedure with the authentication message (step 3) and Chrome stops the sequence returning to the user ERR_INVALID_AUTH_CREDENTIALS. It looks like there is something in the KB code that breaks the NTLM authentication.

Windows 10 users also report that KB3194496 kills the Ethernet connection. The OS usually displays the error message “Ethernet Doesn’t Have A Valid IP Configuration”, and none of the workarounds available on the almighty Internet really work. Thank you, Selatious for the tip.

KB3194496 killed my Ethernet connection. The odd thin when it first happened I had outlook and working but no browsers. Did a Win diagnostic fix and lost complete connectivity. Was running off the router so connected directly to the modem with no luck. Win informed me that ‘Ethernet Doesn’t Have A Valid IP Configuration’ I worked on every possible solution for a solid day with no luck. […]

Using a friend’s wireless laptop, I hunted for solutions online, none of which solved the my Ethernet connection. None worked. As a last resort before I went out a purchased a WiFi card or dongle, I did a system restore to before the KB3194496 cumulative update.

That’s all for our article about the KB3194496 issues in Windows 10. This update is far less troublesome than the latest Windows 10 build, but that’s normal, since cumulative updates are stable releases, or at least they should be.

If you’ve encountered other KB3194496 issues that we didn’t mention in this article, feel free to let us know in the comment section below.
