Windows 10 KB4074588 fails to install with error 0x80070bc2 or 0x80070422

Microsoft earlier this week rolled out new cumulative updates to fix the security and non-security bugs in all versions of Windows 10 operating system, Windows 8.1 and Windows 7. According to Microsoft’s forum discussions, Windows 10 KB4074588 is causing error 0x80070bc2 and 0x80070422 on some computers, and the update ultimately fails to install.

This update is only for systems running Windows 10 Fall Creators Update (version 1709). It is also one of the updates shipped by Microsoft on Patch Tuesday. It’s worth noting that the issue is not widespread at the time of writing this story. Only a small number of Windows 10 devices might encounter error 0x80070bc2 or 0x80070422 when attempting to install the cumulative update.

Windows 10 KB4074588: Error 0x80070bc2 and 0x80070422

While the January 2018 update was a nightmare for many users, these bugs aren’t as widespread as they’ve been in past. It’s likely that Microsoft is already aware of Windows 10 KB4074588 error 0x80070bc2 and error 0x80070422. More info would be released soon as all users will install the update in the coming hours.

Microsoft only acknowledges bugs when it’s widespread, but you can expect the fix for this error in March 2018 update. Microsoft on the support page says that Windows 10 Build 16299.248 has just two known issues that would not affect the user experience or show any aforementioned error. One of the known issues in this build is with Windows Update where the system will incorrectly report that the update has failed to install.

We are not aware of any solution to fix 0x80070bc2 or 0x80070422 on Windows 10. We will, however, continue monitoring the forums and keep you posted about the issues with Windows 10 cumulative update KB4074588.

As far as the security improvements are concerned, Microsoft is patching Scripting Engine, Microsoft Edge browser, Device Guard, and the Windows Kernel with February update. Since these updates include security fixes, we recommend users to install them as possible. If you would like to manually upgrade your system, you can do so by downloading the offline installer of this update.
