    Windows won't boot

    Hello! My W-10 computer recently decided to reinstall a bunch of updates that it already had (this actually happened on all three of my PCs running W-10, so I assume it was something from Microsoft? I dunno). Normally not an issue, but on this particular PC Windows now won't boot.

    In case it matters, the following were all performed from the built-in recovery environment that pops up after Automatic Repair fails, not a bootable flash drive or anything else.

    I first tried removing pending Windows updates, which said it completed but did not fix the issue as it had in the past. Then I edited the BCD to force booting into safe mode, but Windows still wouldn't boot (so I removed that flag and rebooted back into the repair environment).

    I then tried running sfc /scannow /offbootdir:C:\ /offwindir:C:\windows\ several times, but each time it said it found errors but couldn't repair them. Last night while I was researching I found an MS MVP wiki article that says (at the bottom) that sfc /scannow doesn't work properly in W-10. Great.

    So I then used an Ubuntu bootable flash drive to copy the Windows directory from a working copy of build 9879 from my laptop to an external HDD, then I ran DISM /Image:C:\ /Cleanup-Image /RestoreHealth /SourceWindows won't boot :D:\Windows (where D:\ was my external HDD). That operation failed, reporting that some hashes were invalid (specifically "CSI Payload Corrupt"; log file is attached). My plan was to come to work today and pull what I know to be valid copies of the two files from my W-10 work computer, but none of the general hash methods (MD5, CRC32, SHA1, SHA256, SHA512, SHA384) report matching values even for what I already had, so I have no way of determining what will be accepted as valid once I get back home to my desktop computer.

    I'm pretty much to the point where I'll just backup files, wipe the drive, and start fresh, but I figured I'd ask here before I do that as I'd REALLY like to avoid having to do so if possible. Any advice at all would be greatly appreciated.

    Thank you in advance!

    Windows won't boot

    The Windows Update folks are great at fixing SFC and DISM problems.
    Their experts hang out here: Windows Updates and Activation - Windows 10 Forums

    The wiki article that you cited says that there's a WSReset.exe command that can be run (from an elevated Command Prompt) to reset SFC. Have you tried that?

    Good luck!
