Latest KB3074665 update fails to install

gazyg asked on

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.

You are aware we're discussing Windows 10, right?  Your instructions to

"Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings, and then click Change PC settings.)"

is how Settings USED to be accessed in Windows 8.1.  There is no swiping action or hot corners in Windows 10, they took all that away.  To get to Settings in Windows 10 one only needs to click on the Settings icon either in the Start Menu or the Taskbar.  The fact that you got how to access Settings wrong really makes me suspect that you don't have any idea what's going on with this nonworking Security Update KB3074665. 

And like the others in the forum, your suggestion of Resetting the PC belies the whole point of Windows 10 installing in-place leaving all applications and programs and settings as they were prior to the upgrade.  And because Windows 10 DOES NOT allow the User to choose which updates to install, this problem of an errant update really snowballs quickly into a PC that is unusable.  I spent ALL DAY July 18 AND the first 12 HOURS of July 19 trying to make this update work.  I was stuck in an update-reboot loop for about five tries.  Finally was able to break in before it had a chance to try to install the update again and at that point I did a system restore to Build 10166.  I had hoped KB3074665 would have shown up before Build 10240 so I could see if it would install prior to upgrading to 10240, but no luck.  So I AGAIN went through the FIVE HOUR process of upgrading to Build 10240.  After the upgrade to 10240 completed it once again became entangled in trying to install KB3074665 without success.  I'm now dead in the water.  I cannot allow any other updates to be installed at this point because it will always try to install KB3074665 first and screws it all up.  This is not funny.  It is now less than a week before final release and as far as my experience (and by reports on various MS Forums), this has been the WORST Build to date.  Nothing but troubles.  Please fix this.
