[SOLVED] Windows 7 Pro SP1 x64 KB4534310 fails with 0x80073701 error

ak84 · May 6, 2020

Dear Sirs!

I have encountered problems with Windows 7 automatic updates.
KB4534310 installation repeatedly fails with 0x80073701 error. I have tried all the options Microsoft offers (including WindowsUpdate.diagcab and catroot2 removal) with no luck.
So i'm seeking help from Sysnative gurus.
Here is the required info:
CBS.zip is quite large and is available from my NAS: https://chugunium.synology.me:5001/sharing/Dh4ojVsrw

I have one more PC with Windows 7 Pro SP1 x64, it has absolutely no problem with automatic updates.
So i'm looking forward to any assistance from gurus.

What i have tried:
1. Tried a "direct update", i.e. manually download and install update package. Error persists.
2. Ran "sfc /scannow". No system integrity violations have been found.
3. Ran "Windows Update troubleshooter" (WindowsUpdate.diagcab, https://support.microsoft.com/en-us/help/4027322/windows-update-troubleshooter) from Microsoft. Results are as follows:
Windows Update error 0x80070490: Not fixed;
Service registration missing or corrupt: Fixed;
Latest update installation problems: Fixed.
After that the problematic update still can NOT be installed.
4. "Reset" Windows Update system as described in the first reply here: windows update (i believe that "WU troubleshooter" does approximately the same). No luck.

While trying to fix WU issue i have found a couple of interesting articles from Microsoft captioned "How to fix errors that are found in the CheckSUR.log":
https://support.microsoft.com/en-us...he-dism-or-system-update-readiness#manual fix
https://support.microsoft.com/en-us/help/2700601/how-to-fix-errors-found-in-the-checksur-log

Hello and welcome,

Attach the logfile C:\Windows\Logs\CBS\CheckSUR.log to your next reply.

ak84 · May 6, 2020

Hi, PeterJ!
Thanks for the prompt reply. Please see the attached CheckSUR.log. There are a LOT of errors inside.
As far as i understand from reading the MS articles, i'll have to manually download all 800+ missing packages...

Download the attachment fixlist.txt and save it to your desktop.

Post the logfile Fixlog.txt as attachment in your next reply.

Restart the computer.
Check Windows Update again and report the result.
If it fails, attach the zipped cbs.log to your next reply.
