14 DAY TRIAL // Microsoft rolled out Windows 10 cumulative update KB4090913 for systems running Fall Creators Update (version 1709) yesterday to fix a USB device connectivity problem, but as it turns out, the same update also causes some more issues on a number of machines.
At this point, there are isolated reports of failed installs hitting Windows 10 cumulative update KB4090913, and just like it happened with previous CUs, users are complaining of an error reading “We could not complete the update, reverting changes” with code 0x80070643.
Afterward, systems are automatically re-offered the update with another failed install attempt, so they’re pushed into an infinite loop that doesn’t stop until the patch itself is completely hidden and blocked on Windows 10.
“Can't find the cause and now stuck on windows update downloading the update again and if I restart to try and install it it's the same on repeat. fails to install and reverting back,” one user explained on reddit.
Some suggest there’s an issue with AMD processors running the latest versions of Windows 10, though Microsoft doesn’t specifically list any known issues with such hardware.
New cumulative updates coming next week
In addition to the typical failed installs hitting cumulative updates, KB4090913 also causes other problems, including USB devices no longer working correctly after the install.
“Careful guys it broke my mouse Logitech G502 into i uninstalled the update. More less made everything on my desktop unclickable,” one user explained, while another one confirmed the bug with the same mouse, adding that they occasionally get a BSOD.
While originally Microsoft said cumulative update KB4090913 only fixes an issue with USB devices, the changelog has been quietly updated in the meantime to also reveal that it resolves a bug causing some devices to fail to boot with INACCESSIBLE BOOT_DEVICE error.
At the time of writing this article, there are no new known issues added to the KB page. With Patch Tuesday kicking off next week and more cumulative update likely to be released, expect fixes aimed at today’s bugs to be included in the rollout.
