I discovered today that Windows 10 lets you change your mouse cursor’s color as well as its size. You have been able to change the mouse cursor set to a different one since Windows 3, I think, which would allow you to switch the color in a different, less flexible way. This feature is different.
I now have a slightly larger, bright-yellow-with-black-outline mouse cursor on my huge 4K monitor. It is much easier to spot when I am returning to my desk after a break. If only Microsoft implemented the “shake that mouse and the cursor gets bigger” feature from macOS.
