Windows 7 updates failing due to code 80070490

[iAMdma]

Keep failing on most Windows updates I've tried. Failed updates include: KB4534310, KB4539601, KB4524752, KB4537820, and KB4539601. This all started with me trying to upgrade this Windows 7 x86 Pro system to Windows 10. It fails and google searches indicate it's due to failed Windows updates. Searching on error 80070490 leads me to CBS corruption. No errors with SFC /scannow, but several with DISM. See attached CBS.zip with logs. CheckSUR.log shows errors related to KB2952664. I successfully uninstalled KB2952664, but errors remain. HELP!!!

Here's the results of SFCFix:

UPDATE: I've found most of the files I need for Temp\CheckSUR. I'm down to two:

Unavailable repair files:
servicing\packages\Package_for_KB2952664~31bf3856ad364e35~x86~~6.1.24.5.mum
servicing\packages\Package_for_KB2952664~31bf3856ad364e35~x86~~6.1.24.5.cat

The ones in the CAB I found were the ones above, but with "sp1" in the name (...Package_for_KB2952664_sp1~...). I guess I need the ones before the service pack. It did take care of the other missing ones though. Anyone have a link to the msu or cab with those in it? Thanks!

Solved! I was able to find the two remaining files on another computer. Once they were placed, DISM ran clean. What's weird is my Windows updates were still failing, but my main goal was upgrading to Win10 and once DISM showed now errors, the upgrade worked!
