Since updating my Surface Book (i7, 256gb) with Microsoft's 11/18 updates, I've noticed that when I do an SFC scan, I get notified that it found corrupt files but was unable to repair them. I did a complete reset and reinstalled everything, including the most recent firmware update, and when I did another SFC scan, I once again received the same message that it found corrupt files but was unable to repair them. Is anyone else having this problem? Is there something else I can try to fix this? Thanks for your suggestions/comments.
