Windows 10 KB4103727 installation issues

Microsoft recently released new cumulative updates for all supported versions of Windows 10. While the cumulative updates are supposed to fix bugs, it appears to be causing headaches for users. KB4103721 for Windows 10 version 1803 broked some PCs and it appears that the Windows 10 KB4103727 for Fall Creators Update also fails to install.

The experience of May 2018 patch on Windows 10 Fall Creators Update doesn’t seem to be flawless either. Several users in Microsoft community forum said that the KB4103727 fails to install. It is worth noting that only a small number of users are experiencing such issues and Microsoft hasn’t yet acknowledged the installation problems.

Windows 10 KB4103727 fails to install on some computers, and the users claim that the update downloads, but it won’t finish installing. In some cases, it throws error 0x800706be and 0x80070bc. The number of reports suggests that the same bug happens on several other systems too.

By the looks of things, Windows 10 KB4103727 is hitting the typical installation issues and there are no critical bugs.

Needless to say, the patches for both Windows 10 April 2018 Update (version 1803) and Windows 10 Fall Creators Update (1709) appears to be causing the biggest headaches for users this month. The performance is however flawless after installing the patch.

How to fix Windows 10 KB4103727 installation issues

It appears that clearing the Windows Update cache fixes the installation issues on some PCs. While it’s not generally recommended, but you can manually clear the Windows Update cache and download the patch again. To fix Windows 10 KB4103727 installation issues, and clear Windows Update cache, do the following:

  • Stop Windows update service: Search “Services” in Cortana and open it with administrator privileges. Find Windows Update, and stop it using the right-click menu.
  • Navigate to C:\Windows\SoftwareDistribution\
  • Open the “Download” folder and delete all files in it.
  • Start the “Windows Update” service in the “Services” desktop app.
  • Go to Settings -> Update & Security -> Windows Update and download the updates again.

As noted above, Microsoft hasn’t yet acknowledged the installation issues and the company is only aware of a single bug.

The majority of systems in the Windows 10 ecosystem are still running the Fall Creators Update, but many users are already in the process of upgrading to the April 2018 Update (version 1803).

Windows 10 KB4103727 advances the PC to Build 16299.431. It’s not a big update and there are not too many fixes, but the upgrade is recommended as it includes security patches for products such as Microsoft Edge, Internet Explorer and apparently the OS itself.
