Bootable Windows on ReFS still not ready for prime time due to lack of wider compatibility

That was back in August and since then, there has not been anything too noteworthy in terms of Windows bootability support on ReFS. Meanwhile, Microsoft has also not updated the officially supported ReFS version up from 3.10 yet, and as such, trying to run Windows on any newer ReFS version leads to an immediate crash on the newest Canary build 26040. Apparently, the crash is worse than it was on previous builds as it now throws up no recovery messages either.

It seems like NTFS will be with us for quite a while longer.
