" Dear Dennis,

I was interested in your article about update KB3122947. I am having the same experience with KB3116908 which has failed 9 or 10 times now, with the following error message: 'Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80070570).' This is yet another Cumulative update for Windows 10 Version 1511, dated December 2, 2015. Do you have a set of instructions on how to fix this one? "

My response:

As you've mentioned, KB3116908 is a cumulative update for Windows 10 - and is also marked as a critical update. Unfortunately KB3116908 doesn't want to download on a lot of systems that I've administered, but I have managed to resolve the issue by searching for, downloading, and reinstalling KB3116908 via Microsoft's Windows Update Catalog website. That said, some users may need to reset their Windows Update components for the install to work even after attempting this workaround. I'll explain how to do all of that below.

How to Fix: KB3116908 Failed to Install (Error 80070570)

Here are the steps to fix KB3116908:

  1. First, determine if you are running Windows 10 32-bit or 64-bit. If you already know the answer to this question, you can skip this step. Otherwise do the following: click Start and type in "cmd" (no quotes); wait for CMD.EXE or Command Prompt to appear in the list, then right click it and select Run as Administrator. Next, highlight the text below using your mouse:

    wmic os get osarchitecture |findstr /I bit

    Right click over the highlighted text (above), then select Copy from the dialogue menu. Go back to the administrative command prompt, then right click in the middle of the window and select Paste. The command you copied above will output to the command line. Press Enter on the keyboard to execute the command. If you are running Windows 10 64-bit, it will output "64-bit"; if you are running 32-bit then it will output "32-bit".
  2. Launch Internet Explorer if it is not currently loaded. The Windows Update Catalog site requires Internet Explorer with Active X enabled in order for the website to work properly and so that you can search for and download the KB3116908 hotfix. If you don't use Internet Explorer while visiting the site, you may receive an "untrusted notification" error message (especially if using Firefox, for example).
  3. Once you have Internet Explorer loaded, go to the KB3116908 catalog page.
  4. There should be 3 downloads on the KB3116908 catalog page: a Technical Preview version, one for Windows 10 64-bit, and another for Windows 10 32-bit. Pay attention to the the "Title" field of each, and download the appropriate fix depending on whether you are running Windows 10 32-bit or 64-bit. For example, the 64-bit version is labeled as "Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3116908)" whereas the 32-bit version has no mention of "x32", or such.

    Note: you don't want Cumulative Update for Windows Server 2016 Technical Preview 4 for x64-based Systems (KB3116908) unless you are running the Technical Preview version of Windows 10 (most users are not).
  5. Once the download has finished, go to your download folder and double click on the file to execute it. It should install without any problems and your system should be updated. If you receive any errors during the update, you may need to reset your Windows Update components. In that case, please follow my guide "How to Fix: Windows Update Won't Update", starting at Step #6, and then come back to this article and try again.

That should do it.

Just to play it safe, I would like to confirm that Step #6 in your fine guide "How to Fix: Windows Update Won't Update" to which you refer in the final step above applies to Windows 10 as well as the earlier versions of Windows the guide mentions. Is that the case?

Yes, it applies, and I've made changes to the article to include mention of Windows 10.

While my issues with Windows 10 update were a bit different than those described in this article (Windows 10 would not even download any updates, much less install them -- in fact I couldn't even get them to download manually using Microsoft's Update Catalog), I remembered I had a freeware program that had fixed Windows 8 for me. I ran it in Windows 10 and it fixed my Windows 10 update problems. It's called Windows Windows Repair (available at It allows you to select exactly what you want fixed in Windows. It does have a few hoops you have to jump through, but it explains each step in plain English (a rarity for computer repair apps). But the bottom line for me was that it actually worked and I was able to download and install all 6 Windows 10 updates that previously would not even download (leaving me with an error 0x800706d9 for each recalcitrant Windows 10 and Office update). The only catch was that I had to reset several default programs and file associations. Otherwise, so far, it's been good to go. Just remember to follow the instructions to the letter and the repairs go very smoothly.
