Back in 2015 when Microsoft rolled out Windows 10, the company promised to keep all versions of the operating system up-to-date with fixes, improvements and security changes. Microsoft has improved the way it handles updates for Windows 10, as a result, the software giant is releasing updates more frequently.
Microsoft recently released Windows 10 KB4090913 with improvements and fixes. Windows 10 KB4090913 is available for devices with Fall Creators Update, and it has a bug that crashes some system when attempting to install this update.
Windows 10 KB4090913 fails to install with error 0x80070643, and shows an error reading “we could not complete the update, reverting changes”. When the update fails to install, Microsoft reverts the changes and restores the previous edition of the Windows 10 operating system without removing any of the files.
There are only a handful number of reports particularly from Reddit of failed installs hitting Windows 10 KB4090913. For some, their PC is stuck on a process of downloading and reinstallation, with no proper option to pause the process. If you will try to reinstall the update, it will fail again, and in some cases, the PCs are rushed into an infinite loop that doesn’t stop.
Windows 10 KB4090913 is causing INACCESSIBLE BOOT_DEVICE error
Microsoft has also updated the changelog of this build with one new known issue. The company explains they there’s a issue where some devices will fail to boot with INACCESSIBLE BOOT_DEVICE error.
It’s worth noting that the new cumulative update pushes Windows 10’s Build number to 16299.251, and it comes with an important fix for an issue affecting USB devices.
“Addresses an issue in which some USB devices and onboard devices, such as a built-in laptop camera, keyboard, or mouse, stop working. This may occur when the Windows Update servicing stack incorrectly skips installing the newer version of some critical drivers in the cumulative update and uninstalls the currently active drivers during maintenance,” the software giant.
