kpf, on Windows Public Beta
My understanding is that this is the same release as the earlier, restricted beta. 1069? I think this is a very good sign, meaning that the earlier beta was really very, very close to final "release quality" code. So close they didn't bother to refresh the beta for the public release.
BTW, one of the early vocal complaints about the MSDN beta was that the computer hung when doing a "properties" request on a device. That isn't a problem with Microsoft, that's a problem with the external device file.
