So I've found a frustrating issue. In the past (Windows 7) automounting of disk volumes could be disabled through either
diskpart -> automount disable or
mountvol /N both of which set the Registry key:
Having done the same in Windows 10 Ent LTSB 2016 (1607), even while the registry key is set, the OS happily proceeds to mount and assign drive letters anyway.
I have made sure to run
diskpart -> automount scrub as well as
diskpart -> san policy=offlineall (and checked the relevant registry key) to no avail.
Am I just SOL on this or is there a new 'home' for this setting?
Edit Diskpart output as requested:
DISKPART> automount Automatic mounting of new volumes disabled. DISKPART>
