How to make the cursor or mouse pointer bigger | PCWorld
Windows 10: In the Search field, type mouse. Select Change your mouse settings. In the resulting Settings app, click Additional mouse settings.
Now, whichever version of Windows you’re using, you should be in the Mouse Properties dialog box.
Two useful tabs in the Mouse Property box
Click the Pointers tab. Pull down the Scheme menu and select something. You’ll find a variety of options in different sizes, colors, and outlines. When you select one, it won’t change the actual mouse pointer, but it will display your selection in the box to the right of the Scheme menu. If you really want to see how a pointer looks in actual use, click Apply and mouse around with it a bit.

You’ll find more possibilities in the dialog box’s Pointer Options tab—especially in the Visibility section. Pointer trails can be especially useful in making the pointer more visible.
