Originally started out with Windows Update trying to run, but never finishing. The original message was something like - Windows 10 couldn't be installed. Failed: 1 update. Error(s) found: C1900101-30018 Windows Update encountered an unknown error. This is my sister's machine, and I believe she had cancelled a Windows 10 upgrade at some point, wanting to keep Windows 7. This computer is Windows 7 Home Premium 64-bit.
I have tried using the native Windows Update Repair, Windows Update Diagnostics, new Windows Update Agents, messed around with various options in System Configuration, and tried using the Windows6.1-KB947821-v34-x64.msu file, among other things. Some tools pointed to a problem with Avast, which I have uninstalled, and attempted to wipe out the remnants of. I found this site, and ran SFCFix, which shows the following -

I'm not sure what to do at this point. Any suggestions?
