That seems only slightly less scary than the btrfs on Windows project (which suggests disabling SecureBoot). At least it's from a ZFS contributor (while btrfs on Windows seems like a from-scratch rewrite, ie. all the bugs all over again).

From the comments here I take it people aren't actually using anything with features like snapshots/cow/compression on Windows :-/
