Windows 10 Update Assistant Error 0x8007007e

LifeMushroom · 09 Feb 2018

Hi everyone,

I'm on Windows 10 and the Update Assistant keeps bugging me for months, saying that I'm getting error 0x8007007e.

I tried disabling/uninstalling Avast Antivirus, didn't work. I've restarted. I've tried "sfc /scannow" but I get "Windows Resource Protection could not start the repair service." I've tried it in Safe Mode as well, and it didn't work. I've tried using the Media Creation tool to create an ISO, then running the ISO in the admin account, and I get 'Windows 10 installation has failed'. I've even ran the Windows Update troubleshooter, which looked like it fixed some things, but I still got the error after.

Here is the screenshot:

Here are my system specs:
HP Pavilion dv6 Notebook PC
Model number: A1T68UA#ABA
64-bit
Running Windows 10 version 1607.
Before that I had Windows 7.

Is my laptop simply not compatible with this update? I have no idea what to do now.

Hi,
a. SFC /SCANNOW not running.
Try

If you can get SFC /SCANNOW running - and only if it passes- then try

b. Error 0x8007007e
There's a useful set of ideas here:
How to Fix Windows Update Error 0x8007007e?

If not, then I suggest you proceed to prepare for an in-place upgrade repair install first of your build 1607.
Before attempting that, and noting your system is elderly, please

i. Download and install and run Hard Disk Sentinel (trial) to test your disk
Post a screenshot of its GUI.
To post a screenshot: use the icon above your post to the left of the video icon.
ii. If that's ok from an admin command prompt run
chkdsk c: /scan
Post a screenshot of the result.

Doing net start trustedinstaller worked but I still get the same error with sfc /scannow. I will try HDS now

EDIT: Thanks Caledon Ken I'll try that too

It's a good idea to do the disk checks- Caledon Ken's link focusses on the SoftwareDistribution folder- that's included in the link I posted with a lot more.

However, if your disk proves ok, and chkdsk passes, it would be worth trying Caledon Ken's link first as a short cut. f it works, great- however there may be more to fix as you are so far out of date, something's been wrong for a long while.

Here is the HDS image: http://prntscr.com/ichoo0
I've stopped the Windows Update service for now.
Here's the chkdsk output. https://pastebin.com/szGTLEE6

Good news, after restarting the Update services and deleting from c:\Windows\SoftwareDistribution\DataStore

Before it used to show a ton of updates that failed. What should I do now? Update through the Assistant, or ISO? Or something before that?

As you have a 1709 iso, you can use that. When logged in, mount the iso, and run setup.exe.

As your disk and file system are ok, provided other Windows corruption doesn't affect the upgrade process, you may be lucky and find it works. Worth trying.

Here are the updates that need to download and sometimes fail

Did you try the inplace / upgrade ( setup.exe) ?

If you can't get past the upgrade would you consider a clean install?

Clean installs require effort but one could argue the finished product is better.
