Windows 10: Windows 10 acting like my controller is a mouse

I downloaded DuckStation PS1 emulator today to replay some old favorites but I can't because when my Xbox 360 controller is plugged in the right analog stick moves the mouse and the buttons do various things. When I launch DuckStation I guess it does not recognize that it's a full screen application so the mouse is moving and buttons are being pressed on the desktop. For example, when I press start the emulator asks me if I want to close it instead of acting like a start button in game. This makes it impossible to use the emulator. It's not just this one either. I've tried to use Dolphin Emula

Controller acting like a mouse on windows 10?

I've looked for hours and literally nothing pops up. Any known fix? Basically my controller acts like a mouse, kinda annoying when playing fifa and ****

 

Mouse acts as a controller

Pull the mouse driver, if it continues replace the mouse

 

Mouse acts as a controller

Back in september 2016 i bought a logitech g502, everything has been fine until now.
A week ago it started acting as a controller in certain games such as The Witcher 3.
The game would say "Press A to skip" but would go back to "Press Enter to skip" as soon as I unplugged the mouse.
Also, windows becomes much less responsive when plugged in. for example:

- Deactivates the windows button (the one on the keyboard) (pressing it wont open the startmenu)
- Cant switch to programs by clicking on them in the taskbar
- Search function doesn't open when pressed.

And the lists goes on.

The funny thing is that this happens every computer that I plug it into.
Tried on my new laptop (MSI GS73VR) and it immediately produced the same effects.

I've tried:
- Installing new firmware on the mouse
- Reinstalling drivers
- Renaming xinput1_3.dll (someone said this could work)
- Multiple different USB ports

The problem exists somewhere on the mouse or in the software on it.

Currently the only solution I see is throwing the mouse in the trashcan or launching it into orbit with a trebuchet.

P.S. Never owned a controller, so it isn't some other software playing games with me.
