Same for me - grayed out with the MZMTE512HMHP-000MV (512GB version) firmware EXT42M0Q. Also tried running as admin and all compatibility setting down to Windows 7. Nada. Haven't tried booting into safe mode, but that shouldn't be required.
I would manually upgrade the firmware, but the download site lists only the 830 and 840 series (no 850), and I don't see any obvious firmware files in any Samsung program directory. Checked Program Files (x86), ProgramData, and all likely AppData locations.
Anyone know where to get the 851 series firmware?
