Windows 10: I cannot customize my cursor

I made a .cur picture with 36x36 pixels, and I go to Settings->Devices->Mouse->Additional Mouse Options->Pointers->Customize->Browse and I select my .cur picture, and then clickOpen, it does not change my cursor not even in the preview corner.

I really want to make my own cursor. Please help me...

Custom Cursors

Please keep all the rainbow color looping as they are. It is now perfect. The black border is the best color to use as the outline. It brings a good contrast, making sure that all the colors appears well.







As a reminder, please keep in mind that this cursor set must be suitable for Windows 10 - 19H1 or above, so you must include all the 17 cursor roles in the same set.

As for the animation steps and the number of colors used, make sure that all the 17 cursor roles have all the same colors in the same order and the same animation steps playing the animation at the same speed. Good luck Hopachi and thank you for making this cursor set on my behalf.

 

Custom Cursors


White dotted spinners for the Default Windows cursors (working and busy)

Previews:













*jagged edges are due to GIF image compression, the actual cursors are smoother.

How to install:
Extract/place the cursor files from zip in the cursor folder (usually C:\Windows\Cursors) then got to mouse pointer settings and browse for the installed files after selecting the working and busy states. Apply or even save the new scheme under a new name, to easily switch back between different cursors via the drop-down theme list:

 

Custom Cursors

That's more difficult than I thought. If you know the program, it can be done.
But good news:
I've added the 'speeded-up' version you suggested in original post below:

I like it *Cool, it loops very well, not that worse-case I've expected. That's why testing is important...
I hope @Cesare will like this one as well.
