Windows 10 Update KB4038782 Failed to Install

Windows 10 Update Failed to Install

I’ve got a bunch of computers running Windows 10, but one computer failed to install the update. I tried a few times, but then luckily was able to resolve the problem using the steps below.

How I installed the update

  1. I’m running the 64bit version of Windows 10 and downloaded the offline installer file ‘2017-09 Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4038782)’ from here:
  2. Then I rebooted the computer and logged in as an administrator account.
  3. I then ran the offline installer that I had downloaded (as mentioned in step 1).Windows Update Standalone Installer
  4. Once the installer had completed, I selected ‘Restart Now’.Windows Update Installation Complete

The offline installer file is massive and is over 1GB in size! I can’t remember how long it took to install, but it was quite a while and I’m glad I had the available time.Security Update for Windows

Whilst it was time consuming to deal with this problem, I’m glad the solution was simple.
