Windows 10 Displaying Smaller Sized Icons Despite Source Being 256x256

Hi there,

I like having big, detailed icons in my games folders however, Windows 10 has decided that such a luxury is absolutely not allowed. Despite the fact that I download only icons that are 256x256 or above, Windows 10 loves to RANDOMLY change icons to display the smaller version (see attached image). I have tried clearing the thumbnail cache but that only forces me to redo half of my icons because guess what? Windows 10 got mad that I was trying to escape its stupidity and reverted them to their smaller size. Sometimes I close the folder, open it, close it, and open it again to find that they decided to change in the mere seconds since I last looked in the folder. This is frustrating me to the point of anger. What is the OS doing that keeps changing my icons?

Thanks!

I've set the icon cache in regedit to 8192 and then deleted the icon cache. Nothing.
