Having the same issue:
PC (no laptop) with 32GB RAM, GTX980TI, Windows 7 x64 = Heavy modded Skyrim w/ ENBOOST works fine, rare CTDs.
Updated to Windows 10 x64 Creators Update = Skyrim crashes immediately.
Installed the DX package (link above), still crash.
Deleting the d3d9.dll from gamedir = Skrim runs, but W/O ENBoost.
BTW I'm using ENBoosts proxy library function to load a 2nd d3d9.dll from RCRN.
So... what is the trick?
What is your memory usage? Windows 8/10 is limited to 4096MBs.
