sfc /scannow: Can't fix corrupt files with a Repair Install

Open the file locally in Notepad and search for the word "corrupt" Cut'n'paste only the lines that qualify under the search into a second file and post that instead. If there are a LOT of such things, provide a sample and give the total count. I'm starting to lean toward the idea that you might want to just perform an in-place upgrade repair install instead, if you find a large number of affected items. See this tutorial for more on the repair install: Repair Install Windows 10 with an In-place Upgrade.
HTH,

Alas, that means you're going to have to read through the log to find reports of other failures. "Corrupt" is usually an indicator that the scan finds and fails to replace a corrupted file of some kind in the component store. But that's not your problem, apparently. See if you can find anything worthwhile there. I'll also PM you so you can email me a copy of your file and look it over for you.
