Yeah, Windows 10 hates Fullscreen. Ive had to do that too, mines on app-controlled, but i tried Full and Windowed and both worked fine ? wierd eh.. ?
Coddleeves: I'm the same. I've tried only installing STA:1, verify and repair, installed 1.3 patch and it doesn't even boot to menu, just goes unresponsive.

Doesn't matter if running from GPU or integrated graphics, DX9 updated, tried installing from offline installer. All failed to run.
Ahhh I've figured it out.
My fix was to run the application "dxcfg" in the install folder and set picture mode to "windowed" and it now seems to boot ok, at least to the menu screen anyway!
