KB4103727 bugs

Microsoft rolled out update KB4103727 to Windows 10 Fall Creators Update users this Patch Tuesday, but not all users have been able to install it.

The download process of the Patch Tuesday usually goes smoothly, but when computers restart in order to complete the install, various error codes pop up on the screen such as error 0x80070bc2.

Here’s how one user describes this issue:

KB4103727 keeps failing for me. It installs, I restart, it informs me it failed. Tried three times now, it’s Windows 10 Home on an AMD A6-4400M laptop. Gives error code 0x80070bc2.

This is not the only error code blocking the update. Error codes ox800706be and 0x800700d8 also occur quite frequently preventing KB4103727 from installing.

I have a similar issue. Could not get 1709 Update to install. […] However, I cannot get rid of the following error when I look for updates. Afraid this is blocking any legitimate updates. Below is the message I get when I search for updates and the info on my PC.
There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: 2018-05 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4103727) – Error 0x800700d8″

If you can’t install KB4103727 on your computer, disable your antivirus software, search for updates, install the available updates and then turn on your antivirus protection.

Clean booting your computer may also help. Here’s how to do this:

  1. Go to the search box > type msconfig
  2. Select System Configuration > go to Services tab
  3. Select Hide all Microsoft services > Disable alldisable startup programs
  4. Go to Startup tab > Open Task Manager > Disable all the unnecessary services running thereclean boot windows 10
  5. Restart your computer

If nothing work, you can also run Windows 10‘s built-in update troubleshooter. Go to Settings > Update & Security > Troubleshoot > launch the update troubleshooter.

  • I was having this problem (windows 10 version 1709 error 0x80070bc2 kb4103727 retry/repeat installation failure) until I used the Windows Update Troubleshooter. The troubleshooter is a relatively new component on the Settings > Update menu. It offered several fixes, after a restart, it repaired Windows update.

  • error 0x8007007e. and something with -105 at the end. KB4134661 also fails to install. Troubleshooter does not work, it says there is a problem, but does not give an option to fix it. As for the other solution, “Disable all the unnecessary services running there”, how do I know which ones are unnecessary?

  • This worked for me after I disabled the antivirus software:

    Right-click on Windows key and select Command Prompt (Admin).

    Type the following commands in Command Prompt window. To execute them, press
    Enter after each one.

    SC config wuauserv start= auto

    SC config bits start= auto

    SC config cryptsvc start= auto

    SC config trustedinstaller start= auto

    Finally, restart your PC and try to install the update that was previously returning the 0x80070bc2 error.

  • Nothing works. Strange thing are two updates on same day; KB4103727 ; waiting on shut down and restart + updateIntel(R) Corporation – MEDIA – 12/6/2017 12:00:00 AM – waiting on installation. Tried several times to restart but nothing happens
