From a quick look, it doesn't appear that the MS tool can verify
SHA-256 checksums, which is what Fedora 11 and newer use (the burning
ISOs document needs to be updated, the documentation team is aware of
and working on that).

It's rather unfortunate that there is such a lack of quality tools for
performing checksum verification available on the Windows platform.

I can understand someone being averse to trusting a third party
verification tool, but at the same time, if that person is running
Windows they most certainly have much more to worry about. :)

If you know of a reasonably trusted tool that can verify SHA-256
checksums on Windows, we'd be very interested to hear about it.
