Have you considered trying to recover files that were deleted? Here's someone's free software being promoted for that with handy instructions http://www.easeus.com/data-recovery/recover-decrypt-wannacrypt-encrypted-files.html http://www.easeus.com/data-recovery/recover-decrypt-wannacry..., or you can try Recuva, which is supposed to be particularly good, with a fairly fast deep scan. PhotoRec is where I would probably go for a windows machine myself, it scans slower, but is command line and understands file formats so even if data is partially corrupted it can rebuild and fix. Obviously, run these from a usb drive so you don't overwrite more.
