Change Mouse Scroll Speed in Windows 10

In Windows 10, you can change the number of lines the active document will scroll for each movement of your mouse wheel. Also, you can make it scroll one screen of text at a time. Here is how it can be done.

You can use either the classic Mouse Properties applet, the modern Settings app, or a Registry tweak to configure the number of lines for the mouse wheel scrolling feature in Windows 10. Let's review all these methods.

To change the mouse scroll speed in Windows 10, do the following.

1. Open the Settings app.
2. Go to Devices -> Mouse.
3. On the right, select Multiple lines at a time under Roll the mouse wheel to scroll.
4. Adjust the slider position to specify the number of lines between 1 to 100 lines at a time.  By default, it is set to 3.
5. To configure the mouse wheel to scroll one screen at a time, select One screen at a time from the Roll the mouse wheel to scroll drop down list.

You are done. You can close the Settings app.
