Windows 10: KB4056892 not offered for update; manual install fails 0x80073715

The Meltdown patch has not been offered so far for update on my Win10 Pro (build 1709) laptop. It also fails the PowerShell script that MS provided to check if your system is vulnerable. It is NOT an AMD system, and I'm using Windows Defender for antivirus protection. When Windows Update failed to pull the Meltdown updated, I manually downloaded the KB4056892 cumulative update. When I try running it fails with error 0x80073715. I've tried running sfc /scannow and dism /online /cleanup-image /checkhealth both of which report that Windows is just peachy.

The only other thing to note is that non-security updates were deferred, but I recently turned that off and updated to build 1709.

Any other suggestions before I chuck this thing in a volcano?

Cannot install update KB4056892 because of error 0x80073715

I have Win 10 v 1709 for x64, and when I try to use Windows Update to install KB4056892, it tries to install but then gives me an error 0x80073715. Manually downloading and installing the update also fails, and it simply gives me an error saying that the
update could not install without any details. This is a new PC that I built myself, so there aren't many programs to mess about with Windows (maybe except Bitdefender Total Security but it's on the whitelist), so please help!

 

2018-02 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4074588) - Error 0x80070002

Hi Thor,

Error code 0x80073715 = ERROR_SXS_MANIFEST_IDENTITY_SAME_BUT_CONTENTS_DIFFERENT

The identities of the manifests are identical, but the contents are different.

It’s possible that the
0x80073715 error was caused by an incomplete download.

There are also other possible causes as well, one recent is a known problem that was caused by some changes made to the system by KB4056892 if it had been installed on the device previously.

Check your update history, is KB4056892 listed as installed?

If so try this:

Uninstall KB4056892.

Then in an elevated command prompt type or copy and paste the command below then hit enter (this will take some time to complete).

Dism.exe /online /Cleanup-Image /StartComponentCleanup

After DISM finishes close the command window, then;

Start the regular windows update to let the OS find its updates (it may or may not reinstall ..892) KB4074588 should then install.

If KB4056892 is not listed in your update history let us know and we can go from there.

Either way, let us know how it goes.

Sometimes you need to run the sfc command up to three times with a reboot after each. Did you do that?

 

Ran sfc /scannow three times, with reboots in between. No change. Should I have sacrificed a goat, too?

Also ran Windows Update Troubleshooter twice. Both times it said it found problems and fixed them. Update still fails.

 

As a workaround, try the Windows Update MiniTool (WUMT). I've had it work for me even when Windows Update was hopelessly bollixed on some of my PCs (which, as we all know, happens from time to time here in Windowsland). Give it a try: it's free, and worst case, your circumstances will simply be unchanged.
HTH,

So this laptop is a bit weird. I can dual boot Win10 Pro and Win10 Home. I booted into Home for the first time in a couple of months, and while it still could not find the update, I was able to download and install it manually. Since the Pro install seems to be corrupted, and I don't need to join a domain or anything, I'm just going to nuke it. At least I'm (partially) protected against Meltdown and Spectre now...
