Microsoft has recently released Windows 10 cumulative update KB3193494 in order to bring the KB3189866 saga to an end, but it turns out that there are users who are experiencing issues with this new patch as well.

Some of those who were offered the new cumulative update are reporting problems when attempting to install it, and the way it happens looks very similar to what others have experienced in the past.

In most of the cases, the cumulative update fails to install, and it simply rolls back before getting users back to the desktop. The update is then reoffered and redownloaded before the system is once again rebooted to attempt the install.

Users who couldn’t install the original KB3189866 update were confident that this new one fixes the problems, so they rushed to install it.

“I have already read some issues with this update and that you should install the offline updater. It has the same problem. Microsoft released KB3193494 to resolve the download issue, so I tried again. Still the same problem,” one of them explains on Microsoft’s Community forums.

Post-installation problems
Others are reporting issues spotted after the update successfully installed on their computers and upon removal, everything seems to be returning to normal, which is living proof that this latest cumulative update is the source of the problems.

“The latest update KB3193494 makes my network drive to become inaccessible. When I remove this update, everything goes back to normal. If the update KB3193494 gets reinstalled, the problem comes back,” another user whose computer is experiencing unusual behavior after installing this cumulative update said.

For the moment, this doesn’t seem to be a widespread issue and Microsoft is obviously yet to acknowledge it, but it remains to be seen how many users are actually hit by the reported problems as more install it from Windows Update.
