I'm finding out that very few PC's actually qualify, since they would need level S0-power and some PCI bus that does not use a blacklisted (un-allowed) DMA channel.
I had a quote But you already knew this.
"Device Encryption Support Reasons for failed automatic device encryption: Hardware Security Test Interface failed and device is not Modern Standby, Un-allowed DMA capable bus/device(s) detected"
It mercifully installs anyway, and I am not looking into encrypting my drives (it would be a predictable disaster)
But I'm hoping the updates to come take allowances for the fact that not everyone wants to willingly scramble their drives, not everyone has a notebook listening for a possible "OK cortana"
To another:
I'd think Microsoft would continue supporting windows 10 until the betas expire (in october?) and after that, any support would have to be for a retail package, but I'm only guessing.
