Undoing changes when updating to W10 fro W7 error - 0x8007001f - 0x20006

Hello all, trying to upgrade to W10 from W7, keeping all personal files and programs, but once the install is completing, and the Windows 10 icon is on the screen, the computer restarts, then said undoing changes made, restarts again and I'm back on Windows 7.

A window pops up with this 0x8007001f - 0x20006, looking online it said that I need to make sure all my Windows 7 updates are installed. I am having an issue with one update that keeps failing, the error code that I get from that is saying that I'm missing files.

I ran Checksur.exe, which repaired 11 but I have more than 1000 missing mum files. I also ran SFCfix and got the same report. I tried going to Microsoft Update Catalog to download each missing file, a few worked, and others said that it was not associated with my computer. Attached are my scan logs.

When I ran the Checksur scan again, the mum files that I thought had worked were still on the missing list.

Other things that I have done: unplugged everything from my computer (besides the mouse).
Use Windows Update Troubleshooter.
Deleted the Windows Update Cache.
Disabled all programs from starting up, installed while in Clean Boot State - ran Windows Updates in Clean Boot State (still had the failure to update).

Tried to repair windows 7 via the DVD, it failed and restored everything back to before.

It's not an option for me to do a clean install, need help on getting the missing mum files, so I can update W7 updates, to hopefully have a chance of installing W10.

    Hi there,

    I see you are using the Update assistance tool for the Win 10 update right .
    I would suggest you to Update the BIOS and drivers of the Pc and then run the tool and also it seems you are not interested in clean install which would be a easy option here , you can try the update catalogue and then manually install all the Win 7 updates and then try Updating to Win 10. You can also try the SFC and DISM scans . If none of them works then Clean install is the Only option here .

    Hope this Answers all your queries , if not please do repost back .
