Microsoft recently started pushing out a fresh update intended to improve update reliability for versions of Windows 10 released prior to the April 2018 Update. As described on Microsoft's support site (via Windows Latest / MSPU), the update is rolling out to Windows 10 versions 1507, 1511, 1607, 1703, and 1709.
There are several points to be aware of with this update before installing it, however. Notably, it may reset network settings and "clean up registry keys" that prevent updates from being installed successfully. It also may repair corrupting Windows OS components, as well as compress files in your user profile directory in order to free up disk space for important updates, Microsoft says.
If you're running Windows 10 versions 1507, 1511, 1607, 1703, or 1709, you should be able to grab this update via Windows Update now.
