Accessiblity - Mouse Pointer

1) Go to your start button, then select settings.

 Next, go to accessibility.

Then click "Mouse pointer and touch"

Then as shown in the following image below, you can choose between 4 styles 

1) Standard 

2) Black Cursor 

3) Inverted Cursor 

4) Custom Colour Cursor

You can also change the size of your cursor to make it more visible and easy to track when moving it across your screen.

I prefer to have a custom colour, my chosen colour has been recommend below, this colour makes it so that my cursor is different to anything on my screen and is easy for me to see.
