Is the saved data generated by Windows 10's file history feature isolated from users and administrators? I'm asking this after reading of the recent crypto attack against OSX machines where time machine backups were safe because the files are only accessible to a special user and even with access to the drive the malware wasn't able to encrypt time machine's data store.
I was wondering if Windows 10's feature provides similar protection. There is a similar question to this but the answers simply suggest different backup strategies and don't actually answer the question.
note: I realize that the most secure solution involves backing up to drives that are physically disconnected, there's no need to suggest that - I'm only looking for a specific answer to this question
