VMware ESXi 6.5, Patch Release ESXi650-201703001 (2148989) | VMware KB
So the long and short of it is, guest unmap basically was not working unless you were aligned to 1MB boundaries. Which is why guest unmap sorta worked on windows NTFS 32K or 64K allocation sizes, but never with default 4K. Still not perfect, but 4K NTFS unmap mostly works now.

I wonder if this could be used to fake out windows 2012 r2 to detect a VMware SCSI disk as thin provisioned for TRIM/UNMAP use? Though it would probably still show up in the VM as SSD and not as a thin provisioned disk...

Zero fill and/or SCSI UNMAP
ESXi HWv9 required for guest based SCSI unmap means nobody with free ESXI can do it that way, and still have to do it the old fashioned way.
