Repair Bootcamp Windows 10 0xc0000225
I tried all available fixes, but in the end I had to reinstall. I couldn't either do a repair installation. I had to do a clean install. Despite, it moved all my old files to windows.old and my own folders in c:\ was still there.

This is the second or third time this happens. I'm going to put all important stuff in onedrive and use reinstall as first option.
