Okay, so, for those folks who are dual-booting Windows 10 on their SP3: is Bitlocker working for you? On mine, for both the Win 8.1 and the Win 10 partitions, in modern UI settings Bitlocker shows as suspended (although in Control Panel it shows as turned on). And, I can access files from the other partition without entering the encryption key, and that doesn't seem right. ???
