Latest KB3074665 update fails to install

I've been using Preview builds since December, installed the latest a couple of days ago (Build 10240). Never had any problems with updates before.

Searching through the log shows the last entry as: -

Windows failed to install the following update with error 0x80070003: Security Update for Windows 10 for x64-based Systems (KB3074665)

Tried the following, none of it works: -

  • Windows Update Troubleshooting tool
  • DISM and SFC tools
  • Deleting the contents of the SoftwareDistribution/Download folder to force the files to download again
  • Unplugged all devices
  • Tried installing it 10+ times

I've posted this to the Feedback app also.

I'd just fixed all my other problems creating a new account and now this new problem arises, I was so close to a perfect Windows 10 installation!

Has anyone else got/had this problem?


One other thing.  I found the Windows PowerShell command to list all user accounts (including hidden accounts) with SID.

get-wmiobject -class "win32_account" -namespace "root\cimv2" | sort caption | format-table caption, FullName, SID

The -1071 account, which shows up in the log right before the error (above), is not present in the PowerShell list.  I think this account was removed (perhaps during Windows 8.1->10 upgrade) but references to it are still hanging out in some places, and that is the reason for this error.  I will try to clean it out of the registry and see if that allows the update to install.

Did this solve your problem?

Sorry this didn't help.

Great! Thanks for marking this as the answer.
