So... I've been Using SCP Toolkit to Emulate the 360 controlles with my PS3-Sixaxis controller, since Windows 10 doesn't have direct support to it...
Is there any other way to run it like that that on Windows?
BTW: Steam user here.

No, not really. There are some other drivers available for Windows, like MotionInJoy or whatever it's called, but afaik it's practically impossible to get a version that works properly and does not contain malware. I would stay with SCPToolkit if I were you.
The mod I linked to in my previous comment will not help you under Windows in either case.
